[ovirt-devel] getStats exception in Engine

[Ales Musil]

Hi,
yesterday we have found out that there is exception thrown in getStats. The
host that was hitting this stayed in connecting state infinitely. This is
caused by recent mom version upgrade in vdsm spec. Mom statistic for
'ksmCpu' is reported as double instead of integer.

I have posted workaround [1] for the vdsm until the proper fix is provided.

Thanks.
Regards,
Ales

Cool!

Did you try it with VNC console?  There is better chance with VNC than
with SPICE.

Hi All,

I am failing to run engine-setup due to the following issue:

[ INFO  ] Generating post install configuration file
