Disable the host so that no new VM can be started on this host and so that the rest of the pool knows that the host was disabled on purpose. Migrate the VMs running on the host to other hosts in the pool, or shut them down. After a reboot or host startup Move VMs back to the host vmware workstation 12 autostart vm on boot free appropriate. There is no need to re-enable the host: it is done automatically when it starts.
Step 1 is especially important if High Availability is enforced on your pool. You don't want the other hosts to believe that a host crashed or self-fenced - and take consecutive action - when it's actually planned maintenance. Alternatively, you can also disable HA on the pool for the duration of the maintenance operations to avoid issues caused by HA.
If all your VMs are "agile", that is, they're not tied to local storage or local devices device pass-throughand if there are enough resources on other hosts in the pool, the above can be simplified as:.
This will disable the host, then evacuate its VMs automatically to other hosts. Any manual modification to the configuration files described below may prevent future XCP-ng updates to update the contents of those files. Avoid modifying them and ask for advice if you have a use case that appears to require such modifications. The goal of this special config is to keep the xensource. Now is the most important step: we must disable TX checksum offload on the virtual xen interfaces of the VM.
This is because network traffic between VMs in a hypervisor is not populated with a typical Ethernet checksum, since they only traverse server memory and never leave over a physical cable. The majority of operating systems know to expect this when virtualized and handle Ethernet frames with empty checksums without issue. However pf in FreeBSD does not handle them correctly and will drop them, leading to broken performance.
The solution is to simply turn нажмите чтобы прочитать больше checksum-offload on the virtual xen interfaces for pfSense in the TX direction only TX towards the VM itself. Then the packets will be checksummed like normal and pf will no longer complain.
Disabling checksum offloading is only necessary for virtual interfaces. These are not only unnecessary, but some of them will make performance worse. Now stick the UUID in the following command:. So for our two virtual interfaces the commands to run would look like this:. That's it! For this /4054.txt take effect you need to fully shut down the VM then power it back on. Then you are good to go!
If you ever add more virtual NICs to your VM, you will need to go back and do the same steps for these interfaces as well. This page details how to install XCP-ng as a guest VM inside different hypervisors to test the solution before a bare-metal installation.
It's a pretty standard HVM, but you need to use a vif of ioemu type. Check this configuration example:. The following steps can be performed under VMware Workstation Pro, the settings will remain the same but the configuration will be slightly different.
We will discuss this point at the end of this section about VMware. The first step, and without a doubt the most important step, will be to modify the virtual network configuration of our ESXi host.
Without this configuration, the network will not work for your virtual machines running on your nested XCP-ng. Then select the port group on which your XCP-ng virtual machine will be connected. By default, this concerns the vSwitch0 and the ' VM Network ' group port. These settings can vmware workstation 12 autostart vm on boot free done at the vSwitch itself same configuration menu. By default, the group port inherits the vSwitch settings on which it is configured.
It all depends on the network configuration you vmware workstation 12 autostart vm on boot free to accomplish on your host. Create a virtual vmware workstation 12 autostart vm on boot free and move to the "Customize settings" section. Here a possible virtual machine configuration :. Finally, install XCP-ng /35739.txt usual, everything should work as expected. An additional option is to be added to the virtual machine's.
You will also add the option to enable promiscuous mode for the virtual machine. Be careful, 'ethernet0' is the name of the bridged network interface of my virtual machine, remember to check that it's the same name in your. For this you must also modify the. Replace ethernet0. Check if the virtual machine correctly works by trying to connect using XCP-ng Center and by creating a virtual machine on your nested XCP-ng.
The settings will remain the same for both OS. Unlike VMware, you must first create the virtual machine to configure nested virtualization. Indeed, under Hyper-V, the configuration of the nested virtualization is a parameter to be applied to the virtual machine, it is not a global configuration of the hypervisor.
The configuration of the virtual machine uses legacy components. The consequences are that the performance of this XCP-ng virtual machine will be poor. Once the virtual machine is created, it is possible to enable nested virtualization for this virtual machine. Open a Что hp software for windows 10 удалена Administrator prompt :. Then, it will be about vmware workstation 12 autostart vm on boot free the network to allow guest virtual machines to access to the outside network.
Like VMware, you must first enable the nested virtualization feature on your host before creating your XCP-ng virtual machine. If the command returns "Y", nested virtualization is activated, if not, you should activate it next steps. Firstly, check if you don't have any virtual machine running. Then, unload the KVM module using root user or sudo :. Nested virtualization is enabled until the host is xero app. On recent kernels, when enabling AMD virtualization in the BIOS, it should enable nested virtualization without vmware workstation 12 autostart vm on boot free further configuration.
The configuration of the virtual machine will use mostly emulated components for disks and network. The перейти use case for this is you want to run your network's router as a VM and your network has multiple vlans.
With some help from others in the forums opens new windowI was able to get a satisfactory solution implemented using pfSense opens new window and so this document will discuss how to implement this solution using pfSense as your router. In theory, the same solution should apply to other router solutions, but it is untested. Feel free to update this document with your results. There are two approaches to vlans in xcp-ng. The second is to pass through a trunk vmware workstation 12 autostart vm on boot free from dom0 onto your router VM.
By far, this is the easiest solution and perhaps the "officially supported" approach for xcp-ng. When you do this, dom0 handles all the VLAN tagging for you and each vif is just presented to your router VM as a separate virtual network interface. It's like you have a bunch of separate как сообщается здесь cards installed on your router where each represents a different VLAN and is essentially attached to a VLAN access untagged port on your switch. There is nothing special for you to do, this just works.
If you require 7 vifs or less for your router then this might be the easiest approach. The problem with this approach is when you have many vlans you want to configure on your router. If vmware workstation 12 autostart vm on boot free read through the thread I linked to at the top of this page you'll notice the discussion about where I was unable to attach more than 7 vifs to my pfSense VM. This appears to be some kind of limit somewhere in Xen. Other users have been able to attach more than 7 vifs via CLI, however when I tried to do this myself my pfSense VM became unresponsive once I added the 8th vif.
More details on that problem are discussed in the thread. Another problem with this approach, perhaps only specific to pfSense, is that when you attach many vifs, you must disable TX offloading on each and every vif otherwise you'll have all kinds of problems. This was definitely a red flag for me. Initially I'm starting with 7 vlans and 9 networks total with short term requirements for at least another 3 vlans for sure and then who knows how many down the road.
Having to reboot my network's router every time I need to create a new VLAN is not ideal for the environment I'm working in; especially because in the current production environment running VMware, we do not need to reboot the router VM to create new vlans.
I started my adventures with xcp-ng by diving in head first at home and replacing my home environment, previously ESXi, with xcp-ng. Now I'm in the early phases of working with xcp-ng in the test lab at work. In conclusion, if you have seven or fewer vifs and you're fairly confident that you'll never need to exceed seven vifs then this approach is probably the path of least resistance. On the other hand, if you know you'll need more than seven or fairly certain you will some day. Or you're in an environment vmware workstation 12 autostart vm on boot free you need to be able to create vlans on the fly then you'll probably want to proceed with the alternative below.
This document is about the alternative approach, but a quick summary of how this solution works in xcp-ng:. However note you will need to manually edit a configuration file in pfSense every time it is upgraded. The physical interface you are using to trunk VLANs into the pfSense VM should also not be the same physical interface that your xcp-ng management interface is on.
This is because one of the steps required is setting the physical interface MTU toand this will potentially cause MTU mismatches if xen is using this same physical interface for management traffic byte sized packets being sent from the xen management interface to your MTU network. The problem we face with this solution is that, at least in pfSense, the xn driver vmware workstation 12 autostart vm on boot free for the paravirtualization in FreeBSD does not support So we have to account for this ourselves both in dom0 and in the pfSense VM.
Once you're aware of this limitation, it actually isn't a big deal to get it all working but it just never occurred to me that a presumably relatively modern network driver would not support Anyway, the first step is to modify the MTU setting of the pif that is carrying your tagged vlans into the xcp-ng server from to The extra 4 bytes is, of course, the size of the VLAN tagging within each frame.
Warning: You're going to have to detach or shutdown any VMs that are currently using this interface. For this example, let's say it's eth1 that is the pif carrying all our tagged vmware workstation 12 autostart vm on boot free. Once this is done, attach a new vif to your pfSense VM and select eth1 as the network.
