vhd-util 'failed to coalesce' while XenServer host executing 'create_privatetemplate_from_snapshot.sh'
Hello there,
I'm working on integrating CloudStack 4.0.1 with XenServer 6.0.2.
I have managed setting up a basic network configuration, launching zone,
launching guest instances as well as creating volume snapshots, but
afterward I'm encountering following issue:
The 'create template from snapshot' operation always fail.
The management server log indicates that following Exception has been thrown
during the operation process:
com.cloud.utils.exception.CloudRuntimeException:
create_privatetemplate_from_snapshot failed due to failed to coalesce

With some effort on debugging the management server code, I figured out that
the operation will finally lead to an invocation on the
'create_privatetemplate_from_snapshot.sh' script on the XenServer host. So I
logged into the XenServer host and manually invoked the script with the same
parameter from cloudstack, and it ended up as follow:
[root@xenserver-modaxvnu bin]# sh -x

The 'vhd-util coalesce -p <vhd> -n <vhd>' command failed. It seems that this
is due to incorrect parameter.
Can anybody help me figure out this issue?
Any insight would be appreciated. And, thanks for your patient on reading
this!
Yours sincerely,
