This is a known issue and it was fixed in version no later than 4.5.2. If you search this list for subject line “corrupt DB after VM live migration with storage migration”, you should see some past discussions on it.
Good luck! Yiping On 3/15/17, 10:51 AM, "Tejas Sheth" <[email protected]> wrote: Hi, We have xenserver 6.2 with cloudstack 4.3.1. We had initiated the data disk migration from one primary storage to another. after the operation we were not able to start the VM. when we checked the xenserver storage, we were not able to find the VHD in any of the primary storage. Its a strange behavior i have seen first time, since the production data is missing we need to identify the root cause of the same. NOTE: Even Root disk is also not available in any of the storage hence we are not able to power on the VM at all. we have checked database where metadata is available in database about the root and data disk. following error captured when we start the vm with Data disk. 2017-03-09 11:49:26,964 WARN [c.c.h.x.r.CitrixResourceBase] (DirectAgent-203:ctx-ff911f73) Catch Exception: class com.xensource.xenapi.Types$UuidInvalid due to The uuid you supplied was invalid.
