I have a 3 host gluster replicated cluster that is providing storage for our RHEV environment. We've been having issues with inconsistent performance from the VMs depending on which Hypervisor they are running on. I've confirmed throughput to be ~9Gb/s to each of the storage hosts from the hypervisors. I'm getting ~300MB/s disk read spead when our test vm is on the slow Hypervisors

Hey, I''m experiencing strange problem: non-deterministic PV domain hang, only on some machines (with fast SSD drive). I''ve tried xen-4.1.0 and xen-4.1.1 with many kernels different kernels: VM: - 2.6.38.3 xenlinux based on SUSE package - vanilla 3.0.3 - vanilla 3.1 rc2 dom0: - 2.6.38.3 xenlinux based on SUSE package - vanilla 3.1 rc2 Result always the same: sometimes VM

Hello, I was thinking of creating a wiki page about Xen clocksources and timekeeping.. including dom0, PV guests and HVM guests. Dan and Jeremy: You guys might have some ideas for this page.. please let me know your thoughts :) Subjects to cover: - Xen hypervisor clocksources (hpet, acpi_pm, pit) - Xen dom0 clocksource, ntpd, etc - Xen PV guest clocksources, independent_wallclock, ntpd,

Hi, I''ve still have problems with ACPI(?) on Xen. After some system startup or resume CPU temperature goes high although all domUs (and dom0) are idle. On "good" system startup it is about 50-55C, on "bad" - above 67C (most time above 70C). I''ve noticed difference in C-states repored by Xen (attached files). On "bad" startups in addition suspend
