Archive/Using XenCenter to manage XCP

From Xen
Revision as of 21:08, 11 November 2011 by (talk) (Added categories)

Citrix XenCenter can be used to manage your XCP hosts, just as if it was a Citrix XenServer host.

Many users will note (and be confused by) the fact that XenCenter reports the XCP client's license is invalid or expiring.
In short, don't worry about it, XCP is free and doesn't have a license. It's just a compatibility issue.
You may further note that some features in XenCenter seem to be disabled (like snapshots).

There are some simple fixes described below to resolve these issues.

XCP 1.1 is intended to include built-in fixes for the below compatibility issues.

Fix #1 to fix API version and enable snapshots in XenCenter

From XCP 1.0 RC3 (build number > 40948) you can trick XenCenter by modifying the config file /etc/xensource/xapi_version_override which contains a single line containing the required version number.
The version number to set it to for XenCenter compatibility is 5.6.100. This is the version string of XenServer 5.6 FP1 and SP2, and will work for XCP 1.0 and 1.1.

echo "5.6.100" > /etc/xensource/xapi_version_override
/etc/init.d/xapi restart

Fix #2 license expiry warning in XenCenter

vi /etc/
#Script to fix XCP 30 License expire issue
#Script increases the month value by 1
#By: Ronny L. Bull & Alex Stuart
#Version: 1.0
#Date: 8-9-2011
FUTURE=`date --date="next Month" '+%Y%m%d'`
#stop xapi service
/etc/init.d/xapi stop
#Replace the expiry entry
sed -i "s/\(expiry.\{3\}\)[0-9]\{8\}/\1$FUTURE/" /var/xapi/state.db
#start xapi service
/etc/init.d/xapi start

bash /etc/

This could be setup as an automated task if desired.

Fix #3 to enable the Import feature of XenCenter

Insert the Citrix XenServer disc or mount the ISO on the XCP server

mount /dev/cdrom /mnt
cd /mnt/packages.transfer-vm/
rpm -ivh xenserver-transfer-vm-6.0.0-50762p.noarch.rpm (this RPM may rename with different releases)

You can now use File -> Import from within XenCenter to migrate virtual machines from other technologies such as VMware or Xen Desktop
