From acee2074e9fe4da2731e61a554639e773c04e43a Mon Sep 17 00:00:00 2001 From: Cedric Bosdonnat <cbosdonnat@suse.com> Date: Mon, 5 Oct 2020 16:49:59 +0200 Subject: [PATCH] Backport a few virt PRs (#272) * Fix virt update when cpu and memory are changed If CPU is changed, the memory change would be short circuited. This is a regression introduced by PR #58332 * virt: add VM memory tunning support * avoid comparing string with integer * fix pre-commit failure * Properly fix memory setting regression in virt.update The 'mem' property in the virt.update value should indicate the result of a live memory setting. The value should be an int in KiB. Fixing the code and tests for this. * virt: add stop_on_reboot parameter in guest states and definition It can be needed to force a VM to stop instead of rebooting. A typical example of this is when creating a VM using a install CDROM ISO or when using an autoinstallation profile. Forcing a shutdown allows libvirt to pick up another XML definition for the new start to remove the firstboot-only options. * virt: expose live parameter in virt.defined state Allow updating the definition of a VM without touching the live instance. This can be helpful since live update may change the device names in the guest.
