Re: [libvirt] [PATCH v2] PanicCheckABIStability: Need to check for existence

Commit id '4313fead' added a call to virDomainPanicCheckABIStability() which did not check whether the panic device existed before making a call to virDomainDeviceInfoCheckABIStability() which ended up segfaulting:

Also seen using following sequence: virsh save $dom $file virsh save-image-edit $file add (or remove) a <panic/> line <devices> ... <panic> <address type='isa' iobase='0x505'/> </panic> ... </devices> Signed-off-by: John Ferlan <jferlan(a)redhat.com&gt; --- Changes since v1 - Added !src && !dst check, which results in: error: unsupported configuration: Target domain panic device count '0' does not match source count '1'
