I am pretty new to XenServer so it may just be something silly causing this. Some background first. I have 2 instances of XenServer running on my network. I have an older horsepower server (quadsocket amd opterons 8224s, 64gb of ram) that doesnt support HVM, and a newer consumer grade system on a Gigabyte motherboard, with an AMD A6-6400k and 4gb of ram, that does support virtualization. The second machine was set up to do vmware to xen conversions, since my ESXi license does not allow XCM to export VMs. I am currently migrating from VMware ESXi to XenServer.
Now the horsepower server has been idle for a couple weeks with absolutely no issues. I just got my conversion server running a couple days ago. I noticed my conversion XenServer has been rebooting itself occasionally, with no warning. This morning, before I left for work, i noticed it was completely hung. No response from the local console either, just a blank screen on my monitor, and I had to restart the system to get XenServer to respond again.
I have looked around the net for a similar issue, and all I can find is a similar occurence on Nephalem chipset based Xeon processors. I neither use Xeons nor have any C-state options, that I am aware of, in my bios. Could it be UEFI or something causing my hangs?
I am not sure which logs would be useful to post here, and I dont see anything related to the hang up in my logs, only missing timestamps.
Any and all suggestions are greatly appreciated.
