However you can use it via custom device in libvirt: Just define a domain like following: <domain type='qemu' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0 '> ... <qemu:commandline> <qemu:arg value='-device'/> <qemu:arg value='edu'/> </qemu:commandline> </domain> More reference: https://libvirt.org/drvqemu.html#qemucommand > > -- > Regards, > Bharath > _______________________________________________ > libvirt-users mailing list > libvirt-users(a)redhat.com > https://www.redhat.com/mailman/listinfo/libvirt-users -- Best regards, ----------------------------------- Han Han Quality Engineer Redhat.

Maybe you can refer to former watchdog device patch series: https://www.redhat.com/archives/libvir-list/2009-October/msg00564.html https://www.redhat.com/archives/libvir-list/2017-September/msg00078.html > Thanks, > Bharath > > On Wed, Oct 23, 2019 at 12:57 PM Han Han <hhan(a)redhat.com&gt; wrote: > >> >> >> On Tue, Oct 22, 2019 at 5:41 PM bharath paulraj <bharathpaul(a)gmail.com&gt; >> wrote: >> >>> Hi Team, >>> >>> I am exploring "edu" device in QEMU to add my own custom device.
