[libvirt-users] old, deleted LUN still showing up after a virsh pool-refresh
by Tom Georgoulias 09 Jun '11

09 Jun '11

Today I upgraded one of our KVM physical host servers to Centos 5.6. The other server remains on Centos 5.5. I've configured a storage pool in libvirt to use LUNs from an iscsi storage system as the volumes for each VM. After the upgrade, I decommisioned one of the VMs and removed the LUN from the storage system. Normally after this kind of operation, I simply need to run this command and the server will see that the LUN no longer exists and remove the volume. # virsh pool-refresh --pool=dev-kvm-storage Pool dev-kvm-storage refreshed This works fine on the centos 5.5 host, but the centos 5.6 still lists the old lun in the vol-list and displays zeros for the capacity. # virsh vol-info 7.0.0.26 --pool=dev-kvm-storage Name: 7.0.0.26 Type: block Capacity: 0.00 Allocation: 0.00 Do I need to do something different now for the newer version of libvirt that is included with centos 5.6? Here are the kernel and libvirt versions I'm using: Centos 5.6: kernel-2.6.18-238.9.1.el5 libvirt-0.8.2-15.el5_6.4 Centos 5.5: kernel-2.6.18-194.26.1.el5 libvirt-0.6.3-33.el5_5.3 Any help is greatly appreciated.

[libvirt-users] ANNOUNCE: oz 0.4.0 release
by Chris Lalancette 08 Jun '11

08 Jun '11

All, I'm pleased to announce release 0.4.0 of Oz. Oz is a program for doing automated installation of guest operating systems with limited input from the user. Release 0.4.0 is a bugfix and feature release for Oz. Some of the highlights between Oz 0.3.0 and 0.4.0 are: - Automatic detection/use of cached JEOS images (the previous method required the user of the oz libraries to detect whether the image was cached or not) - Fixes to make Debian installs work for both x86_64 and i386 - Honor user-provided automatic installation files better, by not doing modifications - Use pyparted to generate partitions on newly created disks (if necessary) - Add support for Fedora 15 - Add the ability to supply an initial root/Administrator password to the diskimage - Abort installs after 5 minutes of disk inactivity - Use M2Crypto to generate SSH keys (if necessary) - Some pydoc documentation (more of this to come in the future) - Support for Ubuntu 11.04 - Support for RHEL-6.1 More documentation on Oz (including links on how to obtain it) is available here: http://aeolusproject.org/oz.html For this release, Fedora 14 and RHEL-6 packages are available. Note that I have stopped providing Fedora 13 packages, since that distribution is (or will be) out of support. Also note that to install the RHEL-6 packages, you must be running RHEL-6.1 or later. If you have any questions or comments about Oz, please feel free to contact aeolus-devel(a)lists.fedorahosted.org or me (clalance(a)redhat.com) directly. Thanks, -- Chris Lalancette

[libvirt-users] Resizing ext4 fedora qemu guest
by Alex 07 Jun '11

07 Jun '11

Hi, I have a fedora14 host with a fedora15 guest and I'm trying to resize the /home partition from 200GB to 240GB. I'm relatively new to the virsh/guestfish commands, as well as LVM, although I think I have a reasonable understanding. I have followed the virt-resize directions (http://libguestfs.org/virt-resize.1.html) but it still shows 200GB: # fdisk -l /dev/mapper/vg_custserv-lv_home Disk /dev/mapper/vg_custserv-lv_home: 197.2 GB, 197165842432 bytes 255 heads, 63 sectors/track, 23970 cylinders, total 385089536 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Outside of the guest, I see this: # virt-filesystems --long --parts --lvs -h -a newdisk.img Name Type Size Parent /dev/vg_custserv/lv_home lv 184G /dev/vg_custserv /dev/vg_custserv/lv_root lv 50G /dev/vg_custserv /dev/vg_custserv/lv_swap lv 5.9G /dev/vg_custserv /dev/sda1 partition 500M /dev/sda /dev/sda2 partition 240G /dev/sda The partition is the correct size, but it appears the volume group(?) is not the correct size. fdisk from within the guest also shows the correct size for the device. I've tried resize2fs from within the guest. Does virt-resize understand the ext4 filesystem and how to properly resize it? Is that my problem? I've also tried using guestfish with lvresize-free without success: <fs> lvresize-free /dev/mapper/vg_custserv-lv_home 100 libguestfs: error: lvresize_free: New size (5876 extents) matches existing size (5876 extents) Run `lvresize --help' for more information. I'm really not sure what to do next. Any ideas greatly appreciated. Thanks, Alex

Hi All, I am new using libvirt. I kept on getting the following error when I try to start my VM. Can anyone give me any suggestion on what could went wrong? Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/engine.py", line 498, in run_domain vm.startup() File "/usr/share/virt-manager/virtManager/domain.py", line 573, in startup self.vm.create() File "/usr/lib64/python2.4/site-packages/libvirt.py", line 287, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: internal error Domain mytest didn't show up Thanks, David

[libvirt-users] io=native
by Troels Arvin 02 Jun '11

Hello, Regarding KVM - in particular RHEL 6.1 x86_64: I just did a set of benchmarks comparing the effect of <driver name='qemu' type='raw' cache='none' io='native'/> versus <driver name='qemu' type='raw' cache='none'/> Using Oracle's "orion" tool with an XIV backend, I got: With io='native': Maximum Large MBPS=964.41 Maximum Small IOPS=11797 Minimum Small Latency=7.57 WithOUT io='native': Maximum Large MBPS=727.42 Maximum Small IOPS=7793 Minimum Small Latency=7.56 In other words, setting the io-attribute to 'native' yields a significant performance improvement. I wonder why KVM doesn't simply default to using io='native'. If that can't happen, then I wonder why libvirt doesn't set io='native' for storage attached to a guest after creation. (virt-manager sets io='native' for the first storage, attached during guest setup, but seems to forget for subsequent block-device additions). -- Regards, Troels Arvin <troels(a)arvin.dk> http://troels.arvin.dk/
