These scripts are all python, so you could read them to track down the issue a bit more. You may also want to check with the libvirt users mailing list (https://www.redhat.com/mailman/listinfo/libvirt-users) so see if they can more easily spot the issue.> libvirtError: Unknown failure > -- > > > command used: > > virt-install --nographics --paravirt --name dora --ram 2048 --file > /dora.img --file-size 153 --location > nfs://mydom:/distributions/redhat60/x86_64/ -x > "ks=http://mydom/ks/redhat60-dora.ks ip=x.x.x.x netmask=255.255.255.0 > dns=x.x.x.x gateway=x.x.x.x" -b xenbr0 > > Ideas? >I wonder if it is an issue with one or more of the options that you pass to virt-install? Nothing is jumping out at me, but maybe someone else on the list (or the libvirt list) will have more hints Hope that helps.

The same options work in other nodes with same version of libvirtd* I have posted this issue at libvirtd-users.

I found the solution but not sure why this is happening. All of my domains are named (in /etc/xen) in format : host.mydomain.com I found that one domain has a format host.com . I changed this filename to host.mydomain.com and my problem went away. Do we need to follow some specific format for domain configuration file name? Thanks Paras.

It seems like it is libvirt-specific as Xen shouldn''t care what the filename is. Maybe libvirt devs would have some insight or like to fix that issue...
