Re: [libvirt] [PATCH] xen: Also add sub-type for driver=tap2 in xen-xm

tap2 only handles 'aio', but not 'raw', which must be explicitly given: | $ virsh domxml-to-native yyy.xml > yyy.xm | $ xm new yyy.xm | Error: tap:/srv/xen/xxx.img not a valid disk type | $ sed -i -e 's/tap2:/&aio:/' yyy.xm | $ xm new yyy.xm Fix reading and writing "xen-xm" format for "tap2" by handling it the same as "tap". --- src/xenconfig/xen_xm.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-)
