Re: [libvirt] xen:/// vs. xen://FQDN/ vs xen+unix:/// discrepancy



Hello,

thank you for your answer.

Yes, I run all those commands locally on the same host (xen4).

The problem only occurs after some time of normal operation: just after 
starting xend, libvirtd, ... everything is fine. Then sometime later after 
starting and stoping some domains, the systems gets unresponsive and the 
above described problem occurs: Only than do the different connection types 
provide different data.

To me it looks like some connection between libvirtd / virsh and xen gets 
broken, so no data on running domains can be retrieved any more, until I 
restart libvirtd. After that everything is back to normal until the next 
hickup.

I'v now enabled that and see if I can gather more data.
