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.
