I have this same problem when I upgraded a testing system on May 24. I also
installed:
linux-image-5.17.0-2-amd64 from unstable
This is the error from a (all) VM:
vm: error: failed to set MSR 0xc0000104 to 0x100000000
kvm: ../../target/i386/kvm/kvm.c:2996: kvm_buf_set_msrs: Assertion `ret ==
cpu->kvm_msr_buf->nmsrs' failed.
libvirt-daemon-driver-qemu/testing,unstable,now 8.3.0-1 amd64
qemu-system-x86/testing,unstable,now 1:7.0+dfsg-7 amd64
When I downgraded the kernel to:
linux-image-5.15.0-3-amd64/now 5.15.15-2 amd64 (my previous kernel)
All OK!
