libvirt users - Aug 2013 - Error while adding volume through virsh

Hi,

I was trying to add volume...I got one xml snippet and I modified it
according to my node configuration:

< volume>
<name>testNode/cluster.vmdk </name>
<allocation>0 </allocation>
<capacity unit='G'>2<capacity>
</volume>

Now when I executed "virsh vol-create datastore1
/local/new_volume.xml" one
error message came saying:

"Error: Failed to create volume from /local/new_volume.xml"
Error: internal error: Creation of raw volumes is not supported"

Can anyone tell me what is going wrong here?


Regards,

Varun

What type of pool are you trying to add this volume to? This may be a
case of no one having implemented the volume creation for your
particular pool backend yet.

virsh vol-create without -c option might connecto to the wrong
hypervisor. Try specifing the connection uri.

I am trying to add this volume to ESX pool. I have ESX server and got
connected to it. When I listed the pool the data store of ESX server was
getting listed down. So I was adding this volume to that.
I want to create a domain but for that Matthias replied that I have to add
volume which will put my .vmdk fole there.

Yes Matthias I am connecting to ESX uri first and then I am adding volume
to my ESX data store.

Hi,

Hi Ján,

Thanks a lot for the suggestion. It worked and volume is added to the
datastore. Now if I try to start the node it gives an error saying:

Error: internal error: Could not start domain: FileNotFound - File
[datastore1] testNode/cluster.vmdk was not found."

But .vmdk file exist at this location. What is going wrong here can anyobe
plz suggest. Below is my xml:

<domain type='vmware'>
  <name>testNode</name>
  <uuid>50115e16-9bdc-49d7-f171-53c4d7f91710</uuid>
  <memory>1048576</memory>
  <currentMemory>1048576</currentMemory>
  <vcpu>1</vcpu>
  <os>
    <type arch='x86_64'>hvm</type>
  </os>
  <devices>
    <disk type='file' device='disk'>
      <source file='[datastore1] testNode/cluster.vmdk'/>
      <target dev='sda' bus='scsi'/>
      <address type='drive' controller='0' bus='0'
unit='0'/>
    </disk>
    <controller type='scsi' index='0'/>
    <interface type='bridge'>
      <mac address='00:50:56:25:48:c7'/>
      <source bridge='VM Network'/>
    </interface>
  </devices>
</domain>
