[PATCH] Added support for disk driver
# HG changeset patch # User Sharad Mishra <snmishra@us.ibm.com> # Date 1300902032 25200 # Node ID 1818f2324144b0a0fa21b1eea1a7dabac1a5eb7f # Parent 62c565a5f71453b02cfcd1317e4a186f2ac1c519 Added support for disk driver. With this patch libvirt-cim allows a user to pass disk driver information. Currently a libvirt-cim XML looks like - <disk type='file' device='disk'> <source file='/dev/shm/vhostmd0'/> <target dev='vdX' bus='virtio'/> <readonly/> </disk> with this patch a user can optionally add driver properties to look like - <disk type='file' device='disk'> <driver name='qemu' cache='none'/> <source file='/dev/shm/vhostmd0'/> <target dev='vdX' bus='virtio'/> <readonly/> </disk> Signed-off-by: Sharad Mishra <snmishra@us.ibm.com> diff --git a/libxkutil/device_parsing.c b/libxkutil/device_parsing.c --- a/libxkutil/device_parsing.c +++ b/libxkutil/device_parsing.c @@ -53,6 +53,7 @@ free(dev->type);
