Subject Add vdisk to kvm guest vm but console fail
Date Mon, 09 Mar 2015 09:01:48 GMT
Hi, Dev Team

I play with cloudstack 4.4.2 + centos 7 kvm. It is ok that I deploy an
instance to kvm host, and the console is ok too. 

When I directly add a vdisk via virsh command to this instance, it is ok and
the disk is recongnised but the console in CS UI is fail.

After I remove the vdisk via virsh command from this instance, the console
in CS UI is ok.

How to debug this issue ? Thanks.

My Env:

virsh # pool-list --all
 Name                 State      Autostart 
-------------------------------------------

 lvm-pool-sdb         active     no        

virsh # pool-dumpxml lvm-pool-sdb
<pool type='logical'>

      <owner>-1</owner>
      <group>-1</group>
    </permissions>
  </target>
</pool>

virsh # vol-list lvm-pool-sdb
 Name                 Path                                    
----------------------------------------------------------------------------
--
 vol1                 /dev/lvm-pool-sdb/vol1

I attache disk to i-3-132-VM:
"virsh attach-disk --domain i-3-132-VM --source /dev/lvm-pool-sdb/vol1
--target vdb --targetbus virtio"

And then I open the console of this instance but fail with notice: "Server
Internal Error ".
