A fix for violating a important standard for booting[0] in recently packaged QEMU 5.2 surfaced some issues with Windows based VMs in our forum[1], which seem to be quite sensitive for such changes (it seems they derive lots of their device assignment from ACPI). User visible effects are loss of any network configuration due to windows thinking it was swapped with a new one, and starts with a fresh config - this is mostly problematic for setups with static address assignment. There may be lots of other, more subtle, effects and the PVE admin is also not always the VM admin, so we really need to avoid such negative effects. Do this by pinning the version of any windows based VMs to either the minimum of (5.1, kvm-version) for existing VMs or the kvm-version at time of VM creation for new ones. There are patches in pve-manager for user to be able to change the pinned version themself in the webinterface, so this can now also get adapted more easily if there surface any other issues (with new or old version) in the future. 0: https://lists.gnu.org/archive/html/qemu-devel/2021-02/msg08484.html 1: https://forum.proxmox.com/threads/warning-latest-patch-just-broke-all-my-windows-vms-6-3-4-patch-inside.84915/page-2#post-373331 Signed-off-by: Thomas Lamprecht <t.lamprecht@proxmox.com> |
