Re: [Xen-users] pv guest fails to start after 4.2 upgrade

[tech mailinglists <mailinglists.tech@xxxxxxxxx>]

Hello Travis,

pleas check /var/log/xen/domainname-dm.log. I think that Qemu is needed in this case of a PV guest. I had the same problem yesterday and the reason was that I forgot to install a special dependency in my case libsdl. In my case the boot stucked at some point and it wasn't obvious that it was related to that.

Eventually something in the portage package is wrong. Hope this would help.

Best Regards

I'm running xen on gentoo (3.7.0 hardened) and upgraded from 4.1 to
4.2 yesterday as 4.2 is marked as stable in the portage tree.
Afterwards, I cannot start my guests and get the following error
(currently running 4.2.1).  Any help in troubleshooting would be
greatly appreciated.  Thanks in advance.
