Subject Re: Add virtual disk to kvm guest vm but the console fail
Date Wed, 11 Mar 2015 07:04:48 GMT
Hi Marcus,

Are the tweaks required to use centos7 as a hypervisor documented somewhere?

Does the same count for 4.6 aka master?

I will be looking into centos7 with kvm soon so would be cool to know what has already be
figured out :-)

Thanks, Remi

Also, CentOS 7 is the guest, right? As hypervisor CentOS 7 barely works in
4.5.0 with a bunch of tweaking, but should be just fine as a guest in any
recent cloudstack release.

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
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
797914bf-50ae-328e-9530-cf379313b216 active     no
bcf4214b-059d-4017-861c-17d6d9306e2b active     no
lvm-pool-sdb         active     no

virsh # pool-dumpxml lvm-pool-sdb
<pool type='logical'>
 <capacity unit='bytes'>1999839952896</capacity>
 <allocation unit='bytes'>10737418240</allocation>
 <available unit='bytes'>1989102534656</available>
   <device path='/dev/sdb1'/>
   <format type='lvm2'/>

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 ".
