Re: [libvirt] virsh create and virsh dumpxml certain code location



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 type='file' device='disk'>
      <driver name='tap' type='vhd'/>
      <source file='/root/tapdisk/vhd-f12'/>
      <target dev='hda' bus='ide'/>
</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.
