Re: Xen Unstable on NetBSD



Hello,

Thanks for the hint, the PCI problem was solved by commenting a few
python lines, anyway, I've read in the list archives that there used
to be a /kern/xen/pci, but in my system I only have /kern/xen/privcmd,
/kern/xen/xenbus and /kern/xen/xsd_port, is this because I'm not
setting any pciback devices, or is it related to xen 4.1 support in
NetBSD kernel?

Anyway, after disabling the PCI stuff xencommons and xend start
correctly, but there's some problem with the hotplug scripts. If I try
to create a domu with xm I get the following error:

Error: Device 51714 (tap) could not be connected. Hotplug scripts not working.

Xend.log doesn't show any relevant info (or at least I'm not able to see it):

dmesg doesn't show anything either, not when booting neither when the
domu is shut down. Any help in solving this issue would be

And as far as I can see, xl still has the console problem (as in Xen
4.1.1) when booting PV domains.

Thanks, Roger.
