My suggestion is to go install http://www.lfarkas.org/linux/packages/centos/lfarkas.repo in your /etc/yumconfig.d folder and run yum install virt-manager and maybe few more needed packages. It is GUI for management of virtual machines. It is under the Red Hat's wing and I used it to easily set ALL parameters for install. There is no need for virt-install commands. ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt ___ CentOS-virt mailing list CentOS-virt@centos.org http://lists.centos.org/mailman/listinfo/centos-virt

Re: [CentOS-virt] Virt-install
Version number. It's 0.5.3-10. Current version on lfarkas's repository is 0.7.0-4. I use it (0.7.0) for a month now, I think, and have not seen any issues so far. I also use kvm-84 from his repository and I have mot seen any problems except I am not able to connect with virtsh to qemu:///system, from root, just qemu:///test. All clients are CentOS 5.3 with kernel 2.6.18-128.1.6, but I must keep virtual host (CentOS 5.3) on 2.6.18-92.1.22 kernel because of issues with MB with AMD chipset (I was going to report this but never got the time to prepare all the info needed).

Re: [CentOS-virt] Machine freeze
Hey, I'm wondering if it is possible that your problem is related to mine. Earlier today I had to restart one of our domUs on one of our systems. I used xm shutdown instead of xm destroy and then did xm list to determine if the domU had shutdown or not. Upon issuing xm list a second time, the entire server crashed and rebooted. I've checked the logs and have yet to find anything. I've attached a transcript of the commands as I executed them on the server. The system is running CentOS 5.3 x64 w/Xen (kernel 2.6.18-128.1.6.el5xen). Any thoughts? Thanks, Matt -- Mathew S. McCarrell Clarkson University '10 mccar...@gmail.com mccar...@clarkson.edu 2009/4/7 Maros Timko tim...@gmail.com Hi all, thanks to all for valuable replies. It seems like we identified the issue. We assured that it is not HW related as it was already reproduced on different machines and platforms, with different BIOS versions. We are running a system performance/statistics collector that executes xentop command on Dom0 regularly. This is causing issues. If we execute: xentop -b -d 0.1 /dev/null in multiple instances, it will freeze the system. It was reproduced on CentOS 5.3 (kernel-xen-2.6.18-128.1.6.el5) system.

Sometimes the whole machine freezes without anything in log files, anything on the console. Sometimes really means we cannot define why or when.

Re: [CentOS-virt] Machine freeze
Hi Mathew, I would say no. Our system has freezed completely, it did not reboot. Our issue was caused by concurrent access to scheduler method that created a deadlock.I can see some out of memory messages, do you still have enough memory for Dom0? 2009/4/29 Mathew S.

Re: [CentOS-virt] Machine freeze
Yeah, the Dom0 should have plenty of memory left since only 2-3 GB of memory is being used out of 12 GB installed. The out of memory messages were from the domU that I xm consoled into prior to shutting down that particular VM because it was out of memory. Matt -- Mathew S.
