Hi all,

I have a hardware host running sles11sp3 with XEN hypervisor. I have 4 DomU's running with sles11sp2. This have been running well and without issues for quite a while. During the last month I have been hit by a very strange situation:
Mailserver
- Can be ping'ed
- reponds to ssh and prompts for password. When password has been entered, the prompt does not appear, hitting ctrl-c will show prompt of DomU
- Checking mailservices with rcgrpwise shows all running
- However, no mail can pass - neither out- or inbound
- A simple top command does not show anything, have to break it with ctrl-c
File and print server
- Can be ping'ed
- reponds to ssh and prompts for password. When password has been entered, the prompt does not appear, hitting ctrl-c will show prompt of DomU
- A simple top command does not show anything, have to break it with ctrl-c
- Cannot access any files, since no drives can be mapped, from client

So the DomU's seems to run, but cannot be used, launch anything like top, pass mails. I am really confused. Other DomU's run without issues at same time from same host.

Any ideas or suggestion on where to start looking?
