Unable to start NetWare DomU after patches

[clausbc]

Hi all,

I just patched my sles11 sp2 with all “Needed patches”. My machine is running as a XEN host, and now I cannot boot my NetWare 6.5sp8 DomU (full virt.)
From xend.log:

Any ideas?
Related to XEN version??

Hi all,

tried moving the NetWare DomU to another sles10sp4 host - using dd:

• Here the DomU boots without problems

It seems to be a version issue, XEN or other OS parts issue
Any advice is highly appreciated.

Kind regards

Hi clausbc,

it might be worth to ask that question over at the Novell forums (i.e. http://forums.novell.com/novell-product-discussions/file-networking-services/netware/), where more NetWare folks are hanging out - from your description this seems indeed to be a version problem concerning your combination of Netware and Xen…

Regards,
Jens

[clausbc]

Thanks Jens,
you might be right - my logic tells me though, that it is primarily XEN related.

Hi Claus,

[QUOTE=clausbc;13008]Thanks Jens,

/Claus[/QUOTE]

it is just the “target audience” that may be more helpful. after you all wrote

I can add:

• sles10 and windows DomU’s are OK on the same host

so it’s not that Xen is inoperative on your host. I don’t argue that the latest Xen upgrade has broken things for you - but as other DomUs work, I expect Netware folks to be both more affected and more able to give answers in your case Seems no one of those (the closest I got to Netware was holding a 4.1 CD in my hands) are hanging out here, thus my pointer.

I’m sorry I couldn’t be of more help here.

Regards,
Jens
