On multiple XenServer 5.x setups I’ve been experiencing dropped packets evident as light to medium packet loss on a busy DomU. It only affects heavy network loads on DomU’s and not Dom0. It also doesn’t seem to care about what OS is running; I’m seeing it in Debian, CentOS, and Windows. Since I manage streaming [...]
The original hardware did all kinds of strange things, stuff like SSH not working and RPM checksums failing, random rebooting, ect. I ended up swapping the chassis, mainboard and RAM but kept the HDD’s to avoid an OS reinstall. Now, I’ve gotten this twice on the new box followed by a hard freeze about 2 [...]
