How to debug Ubuntu 8.04 LTS guest crash during install?
by Neil Aggarwal 04 Nov '25

04 Nov '25

Hello: I am using kvm on a CentOS 5.4 server. I am trying to install the TunkeyLinux Core appliance found here: http://www.turnkeylinux.org/core I downloaded the ISO file from the web site. Then, I used this command to intall it: virt-install -n tkl-core -r 512 --vcpus=1 --check-cpu --os-type=linux --os-variant=ubuntuhardy -v --accelerate -c /tmp/turnkey-core-2009.10-hardy-x86.iso -f /var/lib/libvirt/images/tkl-core.img -s 15 -b br0 --vnc noautoconsole When I connect to the VNC console, I get the Turnkey linux options screen. I select Install to hard disk from there and it seems to start the install but crashes during the installer startup. This is repeatable so there has to be a way to debug it. I tried turning on the debug option for virt-install but that did not give me any useful info. Any ideas how to debug this?

kvm-qemu-ev in testing
by Karanbir Singh 19 Dec '15

19 Dec '15

hi, kvm-qemu-ev from virt7-kvm-common-release is now signed and available on buildlogs.centos.org for testing, the corresponding release file is available in the centos/7/extras/ location on buildlogs as well. Once we have some testing, we can push and announce via mirror.centos.org for wider adoption.

Libvirt enhancement requests
by Nux! 08 Nov '15

08 Nov '15

Hi folks, I know you're rebuilding livbirt for the SIG. Would it be possible to enable RBD support in it? I know quite a few cases (in the Cloudstack community) that switched to Ubuntu particularly because CEPH support was missing. The recommendation is to rebuild the rpms, but this is not a viable thing for everyone. E.g. http://blog.widodh.nl/2015/04/rebuilding-libvirt-under-centos-7-1-with-rbd-… Another thing that I noticed on the CentOS ml recently is an alleged lack of hooks, https://www.libvirt.org/hooks.html And last but not least, where could I find the libvirt (s)rpms that the SIG produces?

Differences between qemu-kvm and qemu-kvm-ev
by C. L. Martinez 02 Nov '15

02 Nov '15

Hi all, What are the real technical difference between qemu-kvm and qemu-kvm-ev packages? What are the advantages to use qemu-kvm-ev (if exists someone)? Or qemu-kvm-ev makes sense when is used with ovirt only?? Thanks.

Megacli issue with Xen PERC 5/i Poweredge 2950 II
by Jeremy Martin 12 Oct '15

12 Oct '15

I am having an issue with Megacli when adding or removing virtual disks. I will post a link to fpaste that has the issue shown. In brief whenever i add, or remove, a virtual disk via MegaCli the attempt succeeds and the adapter is configured but the OS remounts dm-0 in read only. dm-0 is my root lv. This issue does not happen if i boot into the default, non Xen, CentOS kernel. On stock CentOS kernel i can add and remove VD's all day without any issue at all. ONLY happens while booted up with the Xen kernel. I have been racking my brain trying to figure this out. Any help is appreciated.
