So today I moved all the VMs across xenbridges 1,2,3. I have none on xenbridge 0 which has all of my management, hearbeat, and migration traffic. I still have the same issue with hosts rebooting.
One example is when creating a windows or linux VM...When the guest gets to the part where it formats its disk, the host its on reboots everytime. This is very frustrating and unfortunate. Ive done all I know to do with what Ive found in the documentation.
Any ideas would be appreciated.
You may have a storage issue. Have you checked your local VM server logs to see if you getting IO errors?
Yea Im worried about the storage being the issue as well.
I just came across this in /var/log/messages
modprobe: FATAL: Module ocfs2_stackglue not found.
Thats the only error I see in that log and the times I see it are right when the host reboots...
fsck.ocfs2 your storage.
Well I caught an error on the console of the physical host. Typically by the time I made it down to the Datacenter the host had already been rebooted. The error was: "PCI-DMA: Out of SW-IOMMU space for...". I found a note on oracle support to add swiotlb=128 to the module line in grub.conf. That seems to have solved my issue for now. We shall see. Thanks for your replies.
