Re: [CentOS-virt] Machine freeze
Karanbir, can you please, in short, explain to me current status of 64-bit CentOS compared to i386? Is it's maturity same as of i386? I started to actively use CentOS when 4.2 was last version. My decision to use i386-only was based on issues with some (or many?) drivers like madwifi for AR5007, it's unavailability for older PC's, my impression in that time was that it was not stable enough, and the main thing was since I decided to create my own mirror of main and third party repositories for internal use, I went with i386. What is actual gain in using X86_64? Performance in %? Main advantages beside performance? The real question is, does it pay off to spend 20-30 GB of HDD space for X86_64 if i386 does the job nicely? Just a sentence or two would be most appreciated. Karanbir Singh wrote: Mathew S.

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] xen
It should be possible. I used virt-manager (GUI) from lfarkas's repository and used iso files to boot everything (it's much faster). It is much easier to set things from GUI. mattias wrote: Can i use a iso to install a os with virt-install? ___ 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

It's only mentioned in the kvm howto - not under the third party repos. And sadly http://www.lfarkas.org/ is empty. I suppose you already know that kvm will be included by default in the upcoming 5.4 release ? It will be provided only for x86_64 though (afaik ...)

[CentOS-virt] virsh can not connect, but virt-manager does
Hi, i am having problems with virsh utility. I have installed 3 KVM virtual OS-es on top of CentOS 5.3 i386 (with kernel 2.6.18-92.1.22.el5.centos.plus from 5.2, necessary on AMD/ATI MB I have). I have compiled KVM modules from lfarkash-es sorce rpm's and libvirt and managers are recompiled from Fedoras repositories. Problem is following: Guests are installed with virt-manager and whenever I start him I can start and login to guest. on virt-manager's GUI says it connects to qemu:///system on localhost. when I try to use virsh with: [drl...@vmaster ~]$ virsh --connect qemu:///system error: failed to connect to the hypervisor same is with root user. It seams I have leftovers from few versions (just find out), I will see to they I reinstalled: [r...@vmaster ~]# rpm -qa *kvm* kvm-tools-83-5 etherboot-roms-kvm-5.4.4-8 kvm-kmod-debuginfo-83-1 kmod-kvm-83-1 kvm-83-5 kmod-kvm-84-1.el5 [r...@vmaster ~]# , but since virt-manager is working this should not cause this problem. I saw this: http://www.linux-kvm.org/page/Running_libvirt_with_KVM where it says to create symlink for /usr/bin/kvm but they point to X86_64 file and I have i386 kernel. I hope someone can help me.
