Hi all,
I asked this on the users list but never got an answer. I was hoping
maybe one of you could steer me in the right direction.
When I have a domU that resides in the auto directory I get 'Error: Device
2049 (vbd) could not be connected' and the domain starts in a paused mode.
I am using Xen 3.0.1. Shutting down domU and restarting has the same
effect. Following is some output from the xm log and an attempted
restart.
On boot I get the following error:
Restoring Xen domains: xen0vm0-64Error: not a valid guest state file: pfn
count read!.
Directly after dom0 reboot:
xen0:/etc/xen/scripts # xm list
Name ID Mem(MiB) VCPUs State Time(s)
Domain-0 0 251 4 r----- 329.4
xen0vm0-64 4 256 1 --p--- 0.0
>From the logs after dom0 reboot:

and so cannot be mounted now.
And an attempt at shutting down the domU and restarting:

xen0:/etc/xen/scripts # xm shutdown xen0vm0-64
xen0:/etc/xen/scripts # xm list

xen0:/etc/xen/scripts #
The system setup
OS: xen0:~ # SPident
CONCLUSION: System is up-to-date!
found SLES-9-x86_64-SP3 + "online updates"
Hardware: Sun V20z, dual cpu AMD64
The virtual machine resides on EMC San space setup with LVM (/dev/sdc
setup as volume group /dev/xensan)
On a dom0 reboot the machine also take a very long time before it shuts
down. This seems related to the /etc/sysconfig/xendomains setting :
XENDOMAINS_STOP_MAXWAIT=600 as it varies depending on what I set this to.
I've tried various other settings in the /etc/sysconfig/xendomains file
but without any luck.
Any help is greatly appreciated.
