HI, yes, wcons opens a graphical console, it could only work in the graphical user interface environment, if you are using a command line interface, you could probably try "rcons". I will work with some xCAT developers to see how should we update the wiki to explain hypervisor table configuration.
Thanks,

Thanks Li!
By the way, does this bring up a graphical console?
[root@xcat log]# makeconservercf kvm1
[root@xcat log]# wcons kvm1
$DISPLAY not set[root@xcat log]#
I'm just trying to access a terminal type console :o).
Do you know how can i do that?
p.s. please also update the wiki to explain how you must configure the
hypervisor table, otherwise you won't be able to list the vms on each
hypervisor! :o)
Thanks,
Luis

HI,
The command name is "makeconservercf", not "mkconservercf". I searched
the xCAT documentation wiki and updated all the references for "
mkconservercf" to "makeconservercf". Thanks for pointing out this
problem .

Re: [xcat-user]
Problem running
kvm vms
Oh k, figured out what the problem was.
Here's the solution (in case anybody bumps into the same issue):
- in kvm_nodedata, i had a reference to "br0". I changed the table and
updated to "virbr0" and it worked!
- as for the error i was having with listing the vms in my hypervisor,
it was because i did not have a valid entry in the "hypervisor" table:
[root@xcat bla]# tabdump hypervisor
#node,type,mgr,netmap,defaultnet,cluster,datacenter,preferdirect,comments,disable
"i11","kvm",,,,,,,,
"i12","kvm",,,,,,,,
By the way, i don't seem to have the "mkconservercf" command
(referenced in the "XCAT Virtualization with KVM" tutorial) in my
system. Any thoughts on that?
Best,
Luis
