Hello all.

I'm trying to workaround the problem reported here:

https://gitlab.com/qemu-project/qemu/-/issues/1198

but I did not find out how to start up the VM with the option -machine smm=off like sead on the lsit above. I guess that it is possible to run the command using the qemu command but I think that I will lose the management of it. It is possible to startup up a VM with this option using the oVirt GUI ou virsh?

I think oVirt allows you only to modify the corresponding "-cpu ..." options for the corresponding qemu-system-x86_64 executable through edit vm --> custom properties --> add extra_cpu_flags custom property. The "-machine ..." options are indirectly set when you choose between I440FX or one of the Q35 options in Chipset/Firmware Type. That said, it seems the bug you pointed out has been fixed in kernel 6.2 What kind of OS/kernel are you using in your hypervisors? Eg in CentOS Stream 9 it seems it has been fixed since 5.14.0-275.el9 * Thu Feb 16 2023 Herton R. Krzesinski <herton@redhat.com> [5.14.0-275.el9] . . . - KVM: x86: smm: preserve interrupt shadow in SMRAM (Maxim Levitsky) [2035694] . . . Gianluca
