Tried to migrate a few VMs from existing system to an older host that we threw in the rack to facilitate some server reshuffling. Migration complained about lack of capabilities (which I expected its an older server) but when I looked at what I should throw into the xml file I got a core2duo when it should have been at least Penryn or something (Xeon E5345) Of course the VMs work fine with

Hi all I have faced this issue already and the solution was to go back to a old version of qemu-kvm and/or libvirt and things start falling into place but this time I would want to solve this. I have used these versions as per the o/p of the commands below. To jumpstart a new machine which is libvirt capable, it always is a hastle to find out which of the version combination of

Hi everyone, Using the QEMU hypervisor, when a live disk snapshot is requested through libvirt, the request can fail if the underyling qemu binary lacks the snapshotting support. In python, we have something like libvirtError: Operation not supported: live disk snapshot not supported with this QEMU binary I'd like to detect ahead of time if the underlying QEMU can or cannot do

I've installed CentOS 5.4 on my new Lenovo Ideapad S12 (Atom-based 12" notebook) and need to add a quirk to pm-suspend in order for the laptop to actually go to sleep. There's a couple of quirks that work just fine so I really don't have a preference. I found several instructions but most of them have failed me because CentOS's pm-utils is too ancient. Newer versions come

Hi, I cannot have suspend and hibernate working on a Samsung NC10 (netbook) running CentOS 5.4 i386. When I try suspending/hibernating the screen becomes black (with a few logs, like "shrinking memory" for hibernate) and then the computer hangs and I have to force a shutdown with the power button. This wiki page seems to say that it should work out of the box:

Hi all, I've got a weird issue, and I'm trying to confirm if it's a bug, and if so, if there is a workaround until it is fixed. The situation is this: If I virsh reboot <domain> --mode acpi, it will actually reboot the domain cleanly (watching from the console allows me to see the full shutdown messages, followed by a bootup). However, after this point, virsh domstate

Hello, I have a problem with virt-install. I want to use it to create my vm and manage them. But whenever I execute the virt-install cmd I get the error msg mentioned in the subject.

Hi folks, Firstly; apologies in advance for what is a head wrecker of keeping on top of the speculative mitigations and also if this is a duplicate email; my first copy didn't seem to make it into the archive. Also a disclaimer that I may have misunderstood elements of the below but please bear with me. I write this hoping to find out a bit more about the state of the relevant kernel

Hi, I have been trying to install CentOS 5.4 on a Intel SR1530SHS, Intel S3200SH mainboard.. It has a 3 x 1TB sata hotswap drives with LSI software raid onboard. I had configured the LSI to have Sata0 and Sata1 with raid 1 and the third drive as a hotspare drive. Format the harddisk and installation was a breeze. The server rebooted into a blank screen and the cursor just keep blinking. Please

I am trying to connect a KVM-QEMU VM to OVS-DPDK vhostuser port. But, I am encountering a few errors. Since I am very new to libvrt and Linux I am not able to sort them out.
