My vm fails to spawn. nova-commpute.log:

I suspect you're using a very old version of libvirt? Which version
are you using?

Revision history for this message
ms (micromanc3r) said : 		#2

I'm using 0.9.0

I'm going to guess you're missing either ebtables, iptables or gawk. Can you check to make sure they're installed, and if either of them aren't, install it and restart libvirtd and see if that helps.

all three are installed but I did not do anything with them... do I have to set them up somehow?
thx

I tried to upgrade libvirt to 0.9.4 but didn't help

Can you provide the nova.conf you're using?

controller is ubuntu 10.04.3 server and computing node is Debian squeeze with xen hypervisor 3.0.0-1

Revision history for this message
ms (micromanc3r) said : 		#9

sry xen hypervisor is 2.6.32-5

Soren Hansen (soren) said : 		#10

Oh, Xen! That's probably why. Let me check up on that.

Revision history for this message
Soren Hansen (soren) said : 		#11

Yep, that does seem to be the problem. Sorry, that means Xen support through libvirt won't work. :(

Revision history for this message
ms (micromanc3r) said : 		#12

so what do I have to use if I have to work with Xen?

Revision history for this message
Brian Lamar (blamar) said : 		#13

The XenAPI driver requires something like this in the compute node:

--connection_type=xenapi
--xenapi_connection_url=https://10.10.10.10
--xenapi_connection_username=root
--xenapi_connection_password=xenapi_password

That is the XenServer virt layer, which uses xapi. I'm not sure thats available outside of XCP/XenServer yet as Citrix is currently working on getting xapi support into Deiban.

I'm getting exactly the same issue with libvirt 0.8.3 and Xen 4.0.1-2 (on Debian Squeeze).

Can you help with this problem?
