Hi and happy new year!

Just installed TW version:

[Sun Jan  3 17:25:20 2021] qemu-system-x86[3880]: segfault at 28 ip

Trying to create a VM with virt-manager, at the last step after pressing
Finish, the VM is supposed to be created and started, however all I get is:

Jan 03 17:24:57 andreidesktop libvirtd[981]: Unable to read from monitor:
Connection reset by peer
Jan 03 17:24:57 andreidesktop libvirtd[981]: internal error: qemu unexpectedly
closed the monitor

closed the monitor

and dmesg contains:

But running qemu-system-x86_64 directly seems to work OK, a default VM Window
is started and tries to IPXE boot.

This is with qemu-x86-5.2.0-1.1.x86_64 and kernel:
