[libvirt] [PATCH] Power Hypervisor Support for libvirt - minimum set of features
by Eduardo Otubo 07 Jul '09

07 Jul '09

Hello all, This is the initial patch for the driver for IBM Power Hypervisors. The minimum set of features are now implemented: list, list --all and dumpxml. Here is the Changeset since last PATCH I sent: * The URI has changed to: phyp://user@[hmc|ivm]/managed_system. If the system is a HMC+VIOS based, only an HMC authentication will be required. Commands will be sent to VIOS trough HMC command line. And if the system is an IVM based, then just provide the username and password for IVM. * Since the Power Hypervisor has no information about UUID's, I built a little database (uuid_db) to store and associate LPAR ID's with UUID randomly generated by the API. * The command dumpxml is implemented, but there are some informations missing. Fetching informations like fstab, os type, uptime, IP addr and so on, will only be available in a future versions of the HMC system. * The TODO list is now set to implement life cycle functions. Thanks in advance, []'s -- Eduardo Otubo Software Engineer Linux Technology Center IBM Systems & Technology Group Mobile: +55 19 8135 0885 otubo(a)linux.vnet.ibm.com

[libvirt] PATCH: 0/3: Run QEMU guests within a CGroup
by Daniel P. Berrange 07 Jul '09

07 Jul '09

Recent Linux kernels have a new concept of 'CGroups' which is a way to group tasks on the system and apply policy to them as a whole. We already use this in the LXC container driver, to control total memory usage of things runing within a container. This patch series is a proof of concept to make use of CGroups in the QEMU driver. The idea is that we have a 3 level cgroup hierarchy - Top level; contains the libvirtd daemon itself - 2nd level: one per libvirt driver, but dos not contain any processes. - 3rd level: one per guest VM. Contains the QEMU process The host admin can do control on the top level and 2nd level to set an overall system policy. libvirt will then provide APIs / capabilities to control individual VMs policy.

[libvirt] Can't boot guest after adding an IDE storage
by M. Mohan Kumar 07 Jul '09

07 Jul '09

Hi, We installed Fedora 11 guest in an emulated SCSI disk using virt-install. After the installation the guest was shutdown and additional IDE virtual storage was added to the guest. When we try to boot the guest from virt-manager, it tries to boot from the newly added IDE storage (instead of installed SCSI storage) and fails to boot. It seems that how the disk devices are sorted is the problem. There is a bug opened to track this issue: https://bugzilla.redhat.com/show_bug.cgi?id=507271 As dicussed in the bugzilla, ideally there should be a 'bootable' flag for each storage device. Also virt-manager could another option to specify which disk to boot from. Regards, M. Mohan Kumar

[libvirt] Switch from CVS to GIT is done
by Daniel Veillard 07 Jul '09

07 Jul '09

Thanks to Jim Meyering we now have a new git repository, I deprecated the CVS repository, it's read only, you should still be able to keep it around to make patches for a few weeks if needed. The new repo is at: http://libvirt.org/git/?p=libvirt.git;a=summary Unfortunately Jim had to clean up the conversion from CVS that was used previously at git://git.et.redhat.com/libvirt.git so the two are not compatible and the best is to clone a new tree using git clone git://libvirt.org/libvirt.git and then copying over your set of patches with "git format-patch" in the old dir and "git am" to paste them into the new cloned-dir (Jim can certainly provide more details if needed). Let us know if you see something weird in the new tree or on the web site, I have updated the download informations at http://libvirt.org/downloads.html A few things may change but I guess the switch is done at this point, Many thanks to Jim for maintaining the old tree and the migration !

[libvirt] Save and restore with KVM!
by Erkan Unal 06 Jul '09

06 Jul '09

Hi, First of all, I want to ask: is there a libvirt user mailing list? I generally see people exchanging ideas on development of libvirt in this mailing list. So feel free to direct me to the right place if this is not the main mailing list for these kind of questions. I am having problems with save and restore commands in virsh when I try to save and restore KVM virtual machines. After I initiate restore operation, instead of starting where I left during the save operation, it is restarting the VM. Therefore, I need to ask what should I check for these operations to execute correctly? What kind of vm disk types: qcow or vmdk? Which versions of qemu, kvm and libvirt combinations? currently I have libvirt 0.6.5, qemu 0.9.1, kvm-82 on fedora core 8 with kernel version of 2.6.26.8. Thanks, Erkan Unal
