Hello Team,
I am trying to compress a windows 10VM on Eve-ng with the 'virt-sparsify'.
Initial Command Run: virt-sparsify --compress virtioa.qcow2
compressedvirtioa.qcow2
Added debugging and ran again with '-v -x' parameters to get output.
Please see the attached file.
apt list --installed | grep libguest
libguestfs-perl/focal,now 1:1.40.2-7ubuntu5 amd64 [installed,automatic]
libguestfs-tools/focal,now 1:1.40.2-7ubuntu5 amd64 [installed,automatic]
libguestfs0/focal,now 1:1.40.2-7ubuntu5 amd64 [installed,automatic]
The error message is:
qemu-system-x86_64: error: failed to set MSR 0x48f to 0x7fffff00036dfb
qemu-system-x86_64: /build/qemu-0Dw8aG/qemu-4.2/target/i386/kvm.c:2691:
kvm_buf_set_msrs: Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed.
If you search for this error you'll see it's quite common and
indicates that qemu / KVM is broken in some way. You could force TCG
instead:

Probably the long term fix is to upgrade your qemu and/or get your
distro to fix qemu.
