Enable live block migration when using iSCSI volumes
Fix for bug 1160323.
DocImpact
Depends on a version of XAPI supporting relax-xsm-sr-check.
Currently no release versions support this, so the change at
https:/
to the source to enable this. XenServer 6.2 is expected to
support this mode, and possibly some future hotfixes for XenServer 6.1.
It also depends on a configuration change which must be documented and added to devstack:
* Set "relax-xsm-sr-check = true" in /etc/xapi.conf
This commit makes the following changes:
* Attach the SR on the destination host prior to migrate
* Returns the SR-ref from the pre_migrate call (API change)
* Populates the XS VDI map with the sr-ref on the destination host
* Removes the connection to the SR from the source host post-migrate
* Added plugin to determine if iSCSI block migration is enabled
