Hello I have a physical server (Dell Poweredge 1950III) running current CentOS 5.4 x86_64 and the XEN hypervisor, provided by CentOS. This machine has 2 virtual machines installed, both with CentOS 5.4 x86_64. Unfortunatly SSH connections coming both, from an external machine or from DOM0, regularly stall, for a period of some minutes. In other words, while working through SSH, at a given moment everything freezes and after some minutes thaws again. We have several other machines with similar hardware/software configurations, but none of these has similar stalls. Anyway, when attaching the console with "xm console <vm-name>" there are no stalls at all. Does anybody have any suggestion on where to start to trouble shoot this problem? Regards, Peter -- Dott.
