Hello
I have Xen related issues. I try to describe it as best as I can. While transmitting large amounts of data from domU the IO load increases greatly, thus making the domU unusable. The load is significant even on dom0. The performance of cpus and hard drives is not an issue. We have this problem on all servers with diferent hw configurations. Please do you know the reason of this behaviour, do you have any experience whith such problems?
Nope, no such experience with many xen hosts.
How do you measure this "IO load" ? What effects does it have?
What kind of hardware do you have (cpu/mem/nic/disk or raid controller/disks)?
Are you running centos5? latest updates installed?
