[libvirt-users] Automated hashdeep and upgrade for VMs

by Sean Alexandre

Are there any utilities or scripts that automate the process of upgrading VMs, along with other maintenance such as doing a hashdeep check of system files? The key features I'm looking for would do something like: - A: Shut down VM. - B: Do a hashdeep check of system files. - C: Optionally restore VM from a previous backup. - D: Restart VM. - E: Upgrade packages. - F: Shut down VM. - G: Backup VM (for next "C".) - H: Run hashdeep on system files (for next "B".) - I: Restart VM. Other features, but less important, would backup/restore application files as well.

Re: [libvirt-users] kvm/libvirt can't use vmdk files? qemu: 'vmdk' invalid format

by Hammad Siddiqi

Dear All, While trying to run kvm VM using vmdk disk on 6.4 , I got into the following error, error: Failed to create domain from vmdkvm.xml error: internal error process exited while connecting to monitor: qemu-kvm: -drive file=/mnt/vmdkTOKVM/vmdkTOKVM.vmdk,if=none,id=drive-ide0-0-0,format=vmdk,cache=none: 'vmdk' invalid format upon further digging I came across this thread ( https://www.redhat.com/archives/libvirt-users/2011-November/msg00044.html) also qemu-kvm shows that vmdk is supported but all in vain Even if I try running with command line instead of XML I get error though it says it is supported [root@vmdkTOKVM]# /usr/libexec/qemu-kvm -drive file=/mnt/vmdkTOKVM/vmdkTOKVM.vmdk,format=?

by cooldharma06

hi, i am started to exploring libvirt. i am using the version libvirt-1.1.3 and i want to know (or) find the path how the libvirt is creating VM with xen (libxl) in the source. Any guide or reference is available for this. How i can find the path of calling sequence for other operations(api). Guide me to get some idea on debugging the libvirt. Regards, cooldharma06

[libvirt-users] help with VM migration problem: getfd, SCM_RIGHTS

by Joe Linoff

Hi, I am getting the following error when I try to migrate two VM's on my network using virt-manager: Unable to migrate guest: internal error unable to execute QEMU command 'getfd': No file descriptor supplied via SCM_RIGHTS All of the other VM's work just fine. There are 18 and I tested all of them. Version info OS: CentOS 6.4 (2.6.32-358.23.2) [the hypervisors and the guests] Compiled against library: libvirt 0.10.2 Using library: libvirt 0.10.2 Using API: QEMU 0.10.2 Running hypervisor: QEMU 0.12.1 It looks like this might be related to bug 731243 in the red hat bug DB but that was for 0.9.4. If it is related to SELinux permissions, where can I look to fix it? I ran "sealert -a /var/log/audit/audit.log" on the source hypervisor, the destination hypervisor and on the VM itself but no alerts were reported. Any hints would be greatly appreciated, I am not sure what to try next. Thanks, Joe

[libvirt-users] Create RBD Format 2 disk images with qemu-image

by Jon

Hello, I would like to use RBD Format 2 images so I can take advantage of layering. However, when I use "qemu-img create -f rbd rbd:data/foo 10G", I get format 1 RBD images. (Actually, when I use the "-f rbd" flag, qemu-img core dumps, but it looks like that feature may have been deprecated [1]) Is there any way to have qemu-img create RBD Format 2 images or am I better off using `rbd` to create the image then booting from the disk and performing the install, etc.? Thanks for the assist. Best Regards, Jon A [1] http://lists.ceph.com/pipermail/ceph-users-ceph.com/2013-June/002131.html

[libvirt-users] [FWD: [Qemu-devel] KVM Forum 2013 presentations on Google+ (Hangouts on-air)]

by Daniel P. Berrange

FYI for those not able to visit KVM Forum this year, we're attempting to have presentations streaming via G+. No guarantees about success, since we're at mercy of the Hotel net connection, but if streaming fails we'll at least have recordings of all sessions to be uploaded afterwards. Keep an eye on the G+ community mentioned below if you want to try and catch any live sessions. We'll put info in there if we suceed in streaming. Also code reviews next week may be subject to delay, since the Red Hat libvirt team will be at the KVM Forum.

Up. Any ideas ? Thank you De : NEVEU Stephane Envoyé : lundi 14 octobre 2013 10:46 À : libvirt-users(a)redhat.com Objet : migrate & virtlockd Hi all, I'm testing virtlockd with libvirt 1.1.3 and it seems I can't migrate my VMs from the first to my second kvm node (on a NFS storage). Virtlockd is locking my qcow2 : Error : resource busy Lockspace resource 'ea3jkj78.....' is locked As a result my VM is paused. How can I fix this behavior ? Thank you for your help.
