search for: 1200mb

After approx. two weeks of uptime. This host always has some network activity, and when it happened, it was either running or had just finished making backup of about 1200MB (from few ext3 to one ext3 filesystem). kernel was still alive to network pings and services responded, but trying to ssh failed (just hanged there before opening session but after giving last login info). telneting to pop3 port worked, but upon authenticating it also hang - so I'm assuming VF...

I''m installing Xen with the OpenSUSE 10.2 distro and the bigsmp-2.6.18.8-0.13.i586 kernel. However, I occasionally get insane amounts of slowdown (almost 100x) in dom0. On bootup, performance is normal. After an undeterministic period of time, I get this crazy amount of slowdown. I''m not sure why this is the case and I have spent a long time trying to figure it out.

(The list appears to have eaten my previous attempt to send this. Apologies if you receive multiple copies.) The attached patches allow you to use paravirtualised network and block interfaces from fully virtualised domains, based on Intel''s patches from a few months ago. These are significantly faster than the equivalent ioemu devices, sometimes by more than an order of magnitude.
