Can't create a new VM with Virtual Machine Manager - users - Fedora mailing-lists

31 Dec 2018


      I currently run a couple of VMs (one Windows 10 and one Fedora Server)
under QEMU/KVM. I wanted to create a new one and got this:
Unable to complete install: 'internal error: process exited while connecting to monitor: 2018-12-31T14:23:14.816147Z qemu-system-x86_64: can't apply global IvyBridge-IBRS-x86_64-cpu.osxsave=on: Property '.osxsave' not found'

The last line is the key. This is similar to a bug I had a while back and reported at the time:
https://bugzilla.redhat.com/show_bug.cgi?id=1644848
When it happened before I edited the XML file to remove the .osxsave
flag and that solved the problem. However now it's happening with a
fresh VM so there's no XML file to edit. Note that the new VM is a
small Windows test install with no special configuration, i.e.
everything just uses the default settings.
I've posted about this on the VFIO list but haven't received a solution
so far. See
