Gluster performance / Dell Idrac enterprise conflict
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

xen-4.1: PV domain hanging at startup, jiffies stopped
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

Xen clocksources and timekeeping wiki page
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,

High CPU temp, suspend problem - xen 4.1.5-pre, linux 3.7.x
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
