Hi Jim,

Thanks for your reply!

I use xm create to create a tap2 disk and it works well

disk = [ 'tap2:vhd:/root/tapdisk/vhd-f12,hda,w']

but virsh dumpxml can't get anything about the disk

After i apply the patch, i can catch <disk> information by virsh dumpxml

but it seems that it only recognize "tap" only but not tap2

</disk>

Afterwards i try to use this xml file to virsh create VM and no active disk is found.

Moreover, if i change driver name='tap' to 'tap2' in xml myself, virsh seems doesn't support this type and raise error :

error: POST operation failed: xend_post: error from xen daemon: (xend.err 'Error creating domain: Block device type "tap2" is invalid.'

Should i modify the dumpxml and create function if i want to enable tap2:vhd ??

Thank you very much!

Regards,

Ben

Ah yes, I have a patch laying laying around that needs to go upstream.
No better time to do that than now ..
