Re: [PATCH] Support x-vga=on for PCI host passthrough devices

Are you aware that you can add arbitrary options to devices using the <qemu:commandline> support in libvirt? For example: <domain type='kvm' xmlns:qemu=' http://libvirt.org/schemas/domain/qemu/1.0'> ... <devices> ... <hostdev mode='subsystem' type='pci' managed='yes'> <source> <address domain='0x0000' bus='0x01' slot='0x00' function='0x0'/> </source> <address type='pci' domain='0x0000' bus='0x01' slot='0x00' function='0x0'/> <alias name='ua-geforce8800'/> </hostdev> ... </devices> <qemu:commandline> <qemu:arg value='-set'/> <qemu:arg value='device.ua-geforce8800.x-vga=on'/> </qemu:commandline> </domain> This is generally how users make use of unsupportable or not-yet-supported QEMU features while still using libvirt to manage the VM.
