[libvirt] PATCH: Fix bug in error reporting for security driver
by Daniel P. Berrange 15 Jul '09

[libvirt] virsh migrate with libvirt-0.5.1: failed to start listening VM
by Jakub Hrozek 15 Jul '09

15 Jul '09

Hello, I was trying to migrate a KVM/QEMU VM running on a Fedora 10 host to another F10 host. Both machines have identical architectures (x86_64) and are running identical versions of libvirt and KVM (libvirt-0.5.1-2.fc10.x86_64, kvm-74-10.fc10.x86_64). However, the migration fails: # virsh migrate jhrozek-f11-minimal qemu+ssh://someothersystem.example.com/system libvir: QEMU error : operation failed: failed to start listening VM On the target host, the logfile /var/log/libvirt/qemu/jhrozek-f11-minimal.log says: qemu: could not open disk image /var/lib/libvirt/images/jhrozek-f11-minimal.img Which seems rather odd, isn't libvirt supposed to copy the image file? Is this supposed to work? Is there any way to debug the problem? I skimmed through RH Bugzilla and googled a bit but haven't found much clue. Help is appreciated, Jakub

[libvirt] Fedora Virtualization ... some comments and a request for help
by Gene Czarcinski 15 Jul '09

15 Jul '09

First some background ... For the last two to three weeks, I have been working with Fedora (Linux) virtualization ... specifically qemu/kvm. I have been a long time user of VMware and and am hoping to migrate to Fedora Virtualization ("to change my problem set"). I have successfully installed and run CentOS 5.3, Fedora 9, and Fedora 11 in both i386 and x86_64 flavors. I have also installed and run Win2k PRO. All of this worked just fine. Mostly I used virt-manager and only resorted to command-line software when there was no alternative. While I initially had some problems with the way sVirt was doing things, I installed the preview set of packages (libvirt 0.6.5, etc) and it is mostly "good enough" [I did find one "bug" which has been bugzillaed]. Now my problem! I am not sure if I am trying to do something which currently cannot be done, if I have found one or more bugs, or if I just need some help to point me in the right direction. I am trying to "migrate" some VMware guests over to qemu-kvm. I have tried Win2k guests, F9 guests, and F11 guests. Because I sense that the HW version of the disk images may be a problem, I made sure that all of the disk images were version 3 or 4. Using vmware-vdiskmanager, I converted any "split disks" into a single file. I tried using the vmdk files from wmare. I tried converting the files (using qemu-img) to both qcow2 and raw format. I tried using partimage-ng to save (on vmware) and then restore (on qemu-kvm) the disk images. Nothing works! For Win2k, the guest system starts booting and then I get a host system kernel oops. I also tried Win2k with qemu only (no kvm) ... the system started booting and then rebooted ... endlessly. For Fedora guests with LVM, grub brings in the kernel but then immediately fails because it cannot find the logical volumes. For Fedora guests with just /boot, swap, and / partitions, they fail after grub loads the kernel because (IIRC) "setuproot" fails ... it cannot find the root partition. I examined all of the virtual disk images that failed with guestfish and they all looked OK. I also attached some of these virtual disks and booted up under the rescue mode of the distribution DVD and the disks looked OK there too. BUT nothing worked! Then I ran some tests with guests created under qemu-kvm. I created a small guest by installing F11 on a SCSI drive (after doing a dance to swap things around). This scsi install installed and ran fine. I then took the disk image file and attached it to another guest as an IDE drive! This booted up and ran fine. Finally, I used partimage-ng to save the disk image originally created as SCSI and restored it to a different ide attached disk image ... this also booted up and ran fine. There is documentation out there (some, not a lot) which says that I should be able to "migrate" guests from VMware to qemu-kvm. For example: http://www.linux-kvm.org/page/How_To_Migrate_From_Vmware_To_KVM [I tried the above procedure, it did not work either] What am I doing wrong??? Any hints (let alone outright explanations) will be appreciated. BTW, there are statements that only vmdk version 3 and 4 formats ware supported. If that is true, why are there error messages issued when a vmdk file is processed which is not version 3 or 4? Gene

[libvirt] [PATCH] fix generation of .git-submodule-status
by Paolo Bonzini 14 Jul '09

14 Jul '09

When the .gnulib submodule is not initialized, "git submodule status" will prepend a dash in front of the submodule's SHA1. Currently, autogen.sh will then write the dashed SHA1 to its control file .git-submodule-status. This patch fixes the problem; the solution is to... * autogen.sh: Reinvoke git submodule status after bootstrap has initialized the submodule. --- autogen.sh | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/autogen.sh b/autogen.sh index 415f3ec..c824a06 100755 --- a/autogen.sh +++ b/autogen.sh @@ -62,7 +62,7 @@ if test "$t" = "$(cat $curr_status 2>/dev/null)"; then : # good, it's up to date else echo running bootstrap... - ./bootstrap && echo "$t" > $curr_status + ./bootstrap && git submodule status > $curr_status fi # Automake requires that ChangeLog exist. -- 1.6.2.5

[libvirt] Can not shutdown and reboot KVM virtual machine
by Zhang Qian 14 Jul '09

14 Jul '09

Hi, I found I can not shutdown and reboot VMs in my KVM box. It seems I can shutdown a VM which has guest OS installed, but can not shutdown the VM which has no guest OS installed. Reboot can not work with this error message: this function is not supported by the hypervisor: virDomainReboot Any ideas? Thanks! I am using libvirt-0.6.4 and KVM-86. Regards, Qian

[libvirt] Moving Drivers to their respective directories under src/
by Pritesh Kothari 13 Jul '09

13 Jul '09

Hi All, Now since we have moved the repo from CVS => git can we consider moving each driver to its respective directory under src/. The src/ directory is too crowded with more then 150+ base files and more when you compile things. Also is there any way to output the compiled files to a separate out directory instead of keeping everything under src/. That would be advantages in two ways mainly one by reducing the entries in .gitignore (will be just out directory) and secondly will reduce the clutter by keeping src and output separate. Regards, Pritesh
