Re: [Xen-users] 199% CPU in DomU
Hi,
no we also have nagios (v1.3) running in one DomU but this one is runnig
without any problem since months (with 60 servers to check). On saturday
morning (23.09.06) we changed Dom0 to unstable and it's running without
problems until today (25.09.06). I'll tell you about our experiences in
a few days. But the unstable version seems to be very stable :-)
Thanks for answering!
