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.

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: https://libguestfs.org/guestfs.3.html#force_tcg Probably the long term fix is to upgrade your qemu and/or get your distro to fix qemu.
