similar to: Problem with CentOS 5.1 / Xen / Migration : domU time

Hi all, I'm having issue with my Centos 5.1 /Xen installation. I'm having some dom0 running 2.6.18-53.1.6.el5xen (x86_64). On the dom0 where the load is high (more than 70% of total system memory consumed by dom0 and domU) we have a lot of "memory squeeze ". The result is that the domU seems to be blocked (no network/no disk acces/ etc....). Looking for a solution in xen

Hi, I have some xen domU on Centos 5.2 server. For some weeks i had a problem with "xen domU" performances. Indeed my xen domU spend a lot of time in cpu waiting. Reading some informations on the net it seems to come ith I/O heavy load. Using collectd in my domU to monitor the "traffic" on virtual disk and virtuel network i don't see heavy I/O rates. Thinking my dom0

So both "yum upgrade" and "yum update" now are complete and there's no new packages. However, when I attempt to check my version, I'm still showing 5. # cat /etc/redhat-release CentOS release 5 (Final) I remember seeing 5.1 repositories being access for the upgrades. Is it possible my system did not upgrade? # uname -r 2.6.18-53.1.4.el5.centos.plus Thanks, Scott

I have a CentOS 5.1 dom0 running on a machine with two cores and 4gb of memory. It runs three 4.6 domUs and one 5.1 domU. Just out of the blue the other night all the 4.6 domUs crashed, but the dom0 stayed up. I ran xm console (domU-name) and got the Oops information below. I didn't get anything from the 5.1 domU. I think it had been rebooted a few days before and hadn't come up

Short story: Would it be possible to get kernel-debuginfo-2.6.9-67.0.20.EL.x86_64.rpm on di.c.o? I have a need to run crash on a 2.6.9-67.0.20.ELxenU xm dump-core. Long story: Two Dell 6950 (now called R905, 4 Dual-Core AMD Opteron 8200 series) heartbeat/drbd nodes running the stock CentOS 5.2 Dom0. The domU's are the only resources in heartbeat. Dom1 is a perfectly running, updated, CentOS

I converted a physical maschine running CentOS 4.6 to a Xen VM on a CentOS 5 host. Almost everything was running when I decided to rsync /lib and /usr a while later in order to get updated files and get the one or two non-working programs to work. There are differences because of the xenU kernel I didn't think about. I forgot to exclude rpm database and /lib/modules. Because the synced

I am considering creating a web interface for system administration, but it would need a plug-in architecture, adding new UIs as new services are added. I''m thinking about doing this with multiple Rails applications, and I''m curious as to whether mongrel can most multiple apps in a single instance, as opposed to running one for each. Is this possible? Thanks, Mike -- Michael P.

Hi all, sorry to intrude on xen-devel, but I think I need direction from the expertise here. I''ve admin''d Xen servers of various flavors for a couple years, but never seen this before. After a period ranging from several hours to several days, my primary database and development DomU completely locks up. Net disconnects, but CPU(sec) continues to tick in xentop. No errors, and

Hello, I''m running mongrel behind apache via proxypass. Every now and then, a spammer tries to proxy traffic through apache, and for some reason, apache forwards the request to mongrel, even though it''s not a site being hosted by me. At times this seems to cause mongrel to become unresponsive, and all requests to the site then fail with a proxy error until mongrel is

Hey, I''m using mongrel supervised via runit. I''d like to capture mongrel logs with svlogd, which just requires logging to stdout/stderr. But, the Rails app is logging in its own log directory. Is there a way to make both mongrel and Rails log to stdout/stderr? Thanks, Mike -- Michael P. Soulier <msoulier at digitaltorque.ca> "Any intelligent fool can make things

I'm about to try Centos 5 (first time user). Question: I have the 5.0 CD-ROMs, so can I install with them and them update to 5.1 via the internet, or should I use the 5.1 CDs? Thanks. -Tom Tom Browder Niceville, Florida USA

People, I''m trying to set up the tc filters for a PRIO queue. I''m basing it off of marked traffic via iptables.

Hi, I''ve recently deployed a rails app and our platform is Apache 2.2 + mongrel cluster. It seems to be working fine... although no real tests yet. I just recently found out that it is *quite* possible that the live server will not be getting an update to apache 2.2, and the current version is 1.3. So... I''ve installed Apache 1.3 + FastCGI on the dev server and it''s
