We're facing a weird issue with a freshly installed Xen (4.2) system.
The server is an Intel SR1690WB equipped with 4x1Tb HDD and with a RS2BL040 RAID card which configured to use RAID10.
The problem is that any newly spawned paravirtualized guest OS (Debian Squeeze) is working with very high load (70-80% use of CPU, mostly caused by events/0
or events/1
) no matter what they're doing (serving a dynamic page, or just simply downloading an iso file).
Each guest configured to use 2 CPU cores and 4gb RAM.
Just hoping there's some misconfiguration on the Dom0, but what can cause these terrible loads?
Please let me know if i can clarify my question.
