Comment 1 Cole Robinson 2016-03-21 00:36:48 UTC

Since this is for debugging and a reasonably rare case, IMO it should be fine just to use qemu command line passthrough here. Closing, but reopen if anyone disagrees

Comment 2 Shawn Landden 2017-11-21 00:12:47 UTC

I can't find qemu command line passthrough? Where is that feature?

Comment 3 Shawn Landden 2017-11-21 00:13:50 UTC

I am using virt-manager 1.4

Comment 4 Daniel Berrangé 2017-11-21 09:06:36 UTC

This is illustrated here:  https://libvirt.org/drvqemu.html#qemucommand

You nede to use 'virsh edit' to modify the XML to include this, rather than virt-manager.

Comment 5 Cole Robinson 2017-11-21 15:47:49 UTC

or you can use: virt-xml $VMNAME --edit --qemu-passthrough '-gdb ...'

Comment 6 Cole Robinson 2017-11-21 15:48:57 UTC

errrr that's virt-xml --qemu-commandline ...
