[Xen-users] Fwd: XEN 4.2 - DomU Restore after Dom0 reboot not working

[Maik Brauer <maik.brauer@xxxxxxxxxxxxxxx>]

Hi Ian,

may you want to check the Line 258 in the xendomains init script.

It quits with "Restoring Xen domains:/etc/init.d/xendomains: line 258: [: too many arguments"

The current line is: if [ $HEADER = "LinuxGuestRecord" ]; then

I put the $HEADER in brackets like: "$HEADER" and I modified it with the header what XL-Toolkit is using: "Xen saved domain"

So basically the new line 258 looks like this: if [ "$HEADER" = "LinuxGuestRecord" ] || [ "$HEADER" = "Xen saved domain" ]; then

Now the Save and Restore is working perfect. Can you confirm that there is still a bug in the xendomains script?

Thanks a lot.

Cheers,

Maik

Yes that is true. It can be configured via that file. But default it is already configured to work with save and restore. But in my case it is not working. The domain will be save properly. But after Dom0 reboot it will not restore. What can be the issue here?

Hi,

after a reboot of my Dom0 the DomU will not restore after the Dom0 is available again.

The image file has been saved under /var/lib/xen/save

But it will not restore automatically after reboot. If you just try to bring it up manually with

xl restore /var/lib/xen/save/mydomain

it is working and the DomU starts up.

What is the issue that the Domain will not start during reboot.

Thanks.

Cheers,

Maik

Hi, if I recall correctly, this behavior used to be controlled via setting in config file (e.g. /etc/sysconfig/xendomains - it depends on your distro).
