Abstract
It is currently not possible to attach additional virtual disks directly via the webinterface.
What you do in principle:
- Update the VMs configuration data in the LDAP directory
- Manually create the virtual disk
- Regenerate the VM configuration on the node
Step by step
Part I
- In the vm-manager: Expand the VM entry for the VM you want to add an additional disk to and note the UUID below VM name ($VMUUID)
- In a shell: Use
uuidgenand generate a new UUID ($DISKUUID) - Calculate the size of the new disk in bytes:
N * 1073741824for N gigabyte ($DISKSIZE) - Open the URL http://YOURSTONEYCLOUD/phpldapadmin/ and login using
dc=Manager,... - Navigate to:
sstDisk=vda,ou=devices,sstVirtualMachine=$VMUUID,ou=virtual machines,ou=virtualization,ou=services,dc=stoney-cloud,dc=orgusing the tree structure on the left - Click on
Copy or move this entryand choosesstDisk=vdb,ou=devices,sstVirtualMachine=$VMUUID,ou=virtual machines,ou=virtualization,ou=services,dc=foss-cloud,dc=orgasDestination DN - Replace:
- the UUID in
sstVolumeName - and the same UUID in
sstSourceFilewith $DISKUUID (warning: insstSourceFileare at least two UUIDs, replace only the one matchingsstVolumeName) - the value in
sstVolumeCapacityby $DISKSIZE
- the UUID in
- Click on
Createand confirm withCommit - You should get:
Creation successful! - Note the first UUID in the attribute
sstSourceFile($POOLUUID)
Part II
- Login to the VM node on which the VM is/was running
- Run the following command as root:
virsh vol-create-as $POOLUUID $DISKUUID.qcow2 $DISKSIZE --format qcow2 --allocation 0 - You should get:
Vol $DISKUUID.qcow2 created - Run:
chown root:vm-storage /var/virtualization/vm-*/$POOLUUID/$DISKUUID.qcow2 - Run:
chmod g+rw /var/virtualization/vm-*/$POOLUUID/$DISKUUID.qcow2
Part III
- Open the stoney cloud webinterface (vm-manager)
- Shutdown the VM (if not already done)
- Click first on the
edit VMicon and thensave(without changing anything) - Start the VM again
