Hi Everyone,

I installed a fully virtualized VM on my system noted below.  To keep it simple I made it puppy linux.  It runs as expected, including successful reboots.  So… it appears that reboots are broken on my system for paravirtualized systems.  I seem to recall the test install of windows I did about a month ago seemed to work also as it was likewise fully virtualized. 

Any ideas?

Thanks!

Subject: [CentOS-virt] domU reboot leaves VM crashing continually

Greetings,

I’m new to xen virtualization on CentOS, but I have been unable to find the answer to this problem I’m experiencing. 

My setup: AMD quad core (64bit), 8Gb ram.  CentOS 5.3 dom0, CentOS 5.3 domU’s (paravirtualized). 

Dom0 is set up with two NIC’s, the built-in and a PCI card, and I set up xen bridging on both interfaces.  

My domU’s seem to boot up fine, run fine, and shutdown fine.  However, if I attempt a reboot operation, they go into a state where they continually crash on startup.  I have been unable to ascertain why this happens, and I do not know how to fix it when it does happen.  So, my question is twofold:

1) How do I get it out of the continual boot/crash cycle?  Xm destroy doesn’t work, none of the GUI tools work.  So far the only answer has been rebooting dom0, which is not a good answer L

2) Has anyone else seen this/solved this?  Besides being able to manually fix it from #1 above, it sure would be nice to have it able to reboot as expected.  

I haven’t worked with any fully virtualized guests yet, but I will try that pretty soon and see if it evidences the same behavior.

Please let me know what additional information would be helpful or what I can do to facilitate debugging this issue. 

Thanks!
