Re: [Users] Equivalent "virsh" commands to set container parameters like "prlctl set"
Hello, vzctl doesn't have it, but there is "vzmlocal" utility that does the trick. We're working on libvirt though, supposedly libvirt-related utilities should be able to cover functionality that was available through prlctl (virsh, virt-* tools, etc).

Thanks Le 22/04/2022 à 12:42, Pavel Vokhmyanin a écrit : Hello Paulo, Virsh itself doesn't really have a "create" command. It can define domain based on xml. You either compose this xml yourself, or use virt-install to compose it for you. You can also use vzctl or install prl-disp-service and use prlctl. If we're talking about OpenVZ9, you can use these commands for virt-install: I.e. To create a container do the following: 1. Create a disk image with vzpkg. For example: # mkdir -p /vz/mylinuxct # vzpkg create image centos-7-x86_64 /vz/mylinuxct/mylinuxct.hdd Creating Container root image at /vz/mylinuxct/mylinuxct.hdd (centos-7-x86_64) <...> Image was succesfully created at /vz/mylinuxct/mylinuxct.hdd 2. Create the container based on the disk image. For example: # virt-install \ --connect vzct:///system \ --name mylinuxct \ --memory 2048 \ --disk 'path=/vz/mylinuxct/mylinuxct.hdd,boot_order=1,size=64' \ --graphics vnc,port=5903,listen=0.0.0.0 <...> Starting install... Domain creation completed. You can restart your domain by running: virsh --connect vzct:///system start mylinuxct Note, that is "vzct" driver, not "vz" or "openvz". It's a new driver implementation that uses libvzctl and vzevent instead of prl-disp-service integration. Speaking of configuration you mentioned, they are not well documented at the moment. Easiest way for you to figure out how it translates into domain.xml is to use vzctl for configuration, and see how it reflects in the configuration file. Settings were designed to reuse VM (QEMU) configuration schema where possible.
