Hi All, Slightly off topic, but hoping someone can help. I had some users attempt to do a "do-release-upgrade" on a handful of ubuntu 12.04 instance and now they are broken and will not boot.
My hypervisor is XS 6.5. The 12.04 instances had been setup as Other PV 64 (this is from when my hosts were XS 6.02). The error I get is: 2015-07-28 17:41:34,529 DEBUG [c.c.a.t.Request] (DirectAgentCronJob-2:ctx-7459c5c3) Seq 2-4182155203966926850: Processing: { Ans: , MgmtId: 233845174730253, via: 2, Ver: v1, Flags: 10, [{"com.cloud.agent.api.ClusterVMMetaDataSyncAnswer":{"_clusterId":1,"_vmMetaDatum":{"i-3-4-VM":"viridian:true;apic:true;pae:true;acpi:true;nx:false","v-90-VM":"ap ic:true;viridian:true;pae:true;acpi:1;nx:true","r-91-VM":"apic:true;viridian:true;pae:true;acpi:1;nx:true","i-2-28-VM":"viridian:true;apic:true;pae:true;timeoffset:0;acpi:tru e;nx:false","s-117-VM":"apic:true;viridian:true;pae:true;acpi:1;nx:true"},"_isExecuted":false,"result":true,"wait":0}}] } 2015-07-28 17:41:35,063 WARN [c.c.h.x.r.CitrixResourceBase] (DirectAgent-20:ctx-09d05f93) Task failed!

In both of those cases the machine starts and is stuck at the "bios" screen after it says "Boot Device: Hard Disk - success." The root disks are on NFS so I am able to mount them elsewhere and could try to fix grub, but not exactly sure how. If any of you have dealt with this I would appreciate some pointers. Thanks, Carlos
