[libvirt] strange problem only if /usr/sbin/libvirtd is named
by Shi Jin 29 Nov '09

29 Nov '09

Hi there, I am having a very strange problem. I have built a git libvirt for our servers running ubuntu 9.10. The same built works on all servers but one, which gives error information: 21:08:58.827: error : qemudStartup:926 : unable to set ownership of '/var/lib/libvirt/qemu' to user 400:400: Operation not permitted 21:08:58.827: error : qemudStartup:932 : unable to set ownership of '/var/cache/libvirt/qemu' to 400:400: This is because I used the --with-qemu-user and --with-qemu-group options in building libvirt. After hours of debugging, I figured out the problem: as long as the service binary is not named /usr/sbin/libvirtd, I don't have the above errors. For example, I can rename the binary as /usr/sbin/libvirtd.1 or copy it to anywhere else and it works. I am wondering if there is anything so special about this /usr/sbin/libvirtd file name. Also, it is so strange that it works for all other almost identical servers but this particular one. I appreciate your help. -- Shi Jin, PhD

[libvirt] saving domains causes stucks all other commands
by Nikola Ciprich 28 Nov '09

28 Nov '09

Hi, I noticed that using libvirt to save running KVM domain (ie using virsh save ...) causes all other attempts to connect to libvirt and do something to hang till the save finishes. Seems like the issue has been already reported once: http://www.mail-archive.com/libvir-list@redhat.com/msg11431.html but without any resoulution. I've tried libvirt-0.7.4 + also applied bb8d57c68a5d9601058692813c7bdaf83c3d3aff (Fix threading problems in python bindings) which seemed to me might be related but still the problem persists. here's

[libvirt] Howto store schedinfo in the domain definition
by Ralf Nyren 27 Nov '09

27 Nov '09

Hi, Is there support for storing the values accessible with eg virsh schedinfo <domain> --set param=value in the domain definition xml file? Tried to find the syntax definition for this but didn't find anything. Many thanks, Ralf

[libvirt] Problem in handling fast prints from QEMU to stderr
by Saul Tamari 26 Nov '09

26 Nov '09

Hi, I think I spotted a bug in the way libvirtd handles stderr output from QEMU VMs. When starting a VM and QEMU outputs too much output data to stderr (during a given time period), libvirtd will fail and report the following error to /var/log/messages: libvirtd: 13:44:40.695: error : internal error Out of space while reading console log output I looked at the libvirt code a bit and it seems like the stderr-handling code (I think its in qemudReadLogOutput()) is time-dependent and if a 4K buffer overflows it will stop running this VM. As a workaround I added some usleep(250000) near the fprintf() calls (inside QEMU) and I now manage to get the VM running. Is this the way libvirtd is supposed to behave? Thanks, Saul p.s. This was tested on FC11 and libvirtd is version 0.6.2

[libvirt] [PATCH] Xen: Add support for interface model='xenpv'
by Jiri Denemark 26 Nov '09

26 Nov '09

Xen HVM guests with PV drivers end up with two network interfaces for each configured interface. One of them being emulated by qemu and the other one paravirtual. As this might not be desirable, the attached patch provides a way for users to specify that only paravirtual network interface should be presented to the guest. The configuration was inspired by qemu/kvm driver, for which users can specify model='virtio' to use paravirtual network interface. The patch adds support for model='xenpv' which results in type=xenpv instead of type=ioemu (or nothing for newer xen versions) in guests native configuration. Xen's qemu ignores interfaces with type != ioemu and only paravirtual network device will be seen in the guest. A possible addition to this would be to force type=ioemu for all other models which would result in only emulated network device to be provided for an HVM guest on xen newer then XEND_CONFIG_MAX_VERS_NET_TYPE_IOEMU. No type would be configured when model is missing in domains XML. If you think this is a good idea, I'll prepare a second version of the patch.

[libvirt] How do I import an old VM image to a new Install
by Michael N. Moran 25 Nov '09

25 Nov '09

First, I am a casual VM user. I have been using Fedora Core 7 on my Dell laptop for a couple of years with a single QEMU/KVM guest running Windoze XP. I recently installed Fedora 12 on a new hard disk and would like to use my old Windows VM image on the new install. Is there an easy way to do this? I tried copying the image itself (WindozeXpDisk.raw) to the new install and then (naively) looked for an import on the Virtual Machine Manager GUI. The closest that I found was the File->Restore saved machine. I tried that on my WindozeXpDisk.raw image and it failed as follows: Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/manager.py", line 461, in restore_saved_callback newconn.restore(file_to_load) File "/usr/share/virt-manager/virtManager/connection.py", line 649, in restore self.vmm.restore(frm) File "/usr/lib64/python2.6/site-packages/libvirt.py", line 1420, in restore if ret == -1: raise libvirtError ('virDomainRestore() failed', conn=self) libvirtError: operation failed: image magic is incorrect I *can* mount the image using kpartx et. al like this; sudo kpartx -av /var/virt/WindozeXpDisk.raw add map loop1p1 (253:2): 0 31101777 linear /dev/loop1 63 sudo mount -t ntfs /dev/mapper/loop0p1 ./mnt Any clues would be helpful. thank you, mike

[libvirt] crash in libvirtd when assigning PCI device (storage controller)
by Terje Marthinussen 25 Nov '09

25 Nov '09

Compiled libvirt and friends from todays sources on ubuntu 9.10. Was playing around with vt-d and while my MB works fine with ESXi 4, I got some permission issues when I tried the KVM and virt-manager included from ubuntu so I just gambled and compiled everything from latest sources. Things seems to work fine in a normal use case, but if I a PCI device such as a storage controller, libvirtd will get a sigsev. I got the onboard Intel Sata, a PCI Sil Sata card as well as an Areca Raid controller in this machine. I have not tried the Intel Sata device as I am booting from that, but both the other devices causes sigsev. I am sure assigned an intel network card a bit earlier and it actually worked (well, the VM started to boot at least and entered win7 installation without libvirtd crashing), but when I tested that again now, seems like the ethernet card causes the same problem. It is 6AM so will not do a serious attempt at debugging this, just wanted to check if anyone had an idea before I spent more time potentially debugging stuff that is know to not work. >From dmesg: [ 986.341633] device vnet0 entered promiscuous mode [ 986.342897] virbr0: topology change detected, propagating [ 986.342902] virbr0: port 1(vnet0) entering forwarding state [ 986.380733] pci-stub 0000:09:01.0: enabling device (0000 -> 0003) [ 986.380786] pci-stub 0000:09:01.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22 [ 986.422128] pci-stub 0000:09:01.0: restoring config space at offset 0x9 (was 0x0, writing 0xe3c04000) [ 986.422141] pci-stub 0000:09:01.0: restoring config space at offset 0x8 (was 0x1, writing 0x1041) [ 986.422152] pci-stub 0000:09:01.0: restoring config space at offset 0x7 (was 0x1, writing 0x1061) [ 986.422163] pci-stub 0000:09:01.0: restoring config space at offset 0x6 (was 0x1, writing 0x1051) [ 986.422174] pci-stub 0000:09:01.0: restoring config space at offset 0x5 (was 0x1, writing 0x1065) [ 986.422185] pci-stub 0000:09:01.0: restoring config space at offset 0x4 (was 0x1, writing 0x1059) [ 986.422199] pci-stub 0000:09:01.0: restoring config space at offset 0x1 (was 0x2b00000, writing 0x2b00003) [ 987.172975] assign device: host bdf = 9:1:0 [ 987.173054] deassign device: host bdf = 9:1:0 [ 987.206121] pci-stub 0000:09:01.0: restoring config space at offset 0x9 (was 0x0, writing 0xe3c04000) [ 987.206134] pci-stub 0000:09:01.0: restoring config space at offset 0x8 (was 0x1, writing 0x1041) [ 987.206146] pci-stub 0000:09:01.0: restoring config space at offset 0x7 (was 0x1, writing 0x1061) [ 987.206157] pci-stub 0000:09:01.0: restoring config space at offset 0x6 (was 0x1, writing 0x1051) [ 987.206167] pci-stub 0000:09:01.0: restoring config space at offset 0x5 (was 0x1, writing 0x1065) [ 987.206178] pci-stub 0000:09:01.0: restoring config space at offset 0x4 (was 0x1, writing 0x1059) [ 987.206192] pci-stub 0000:09:01.0: restoring config space at offset 0x1 (was 0x2b00000, writing 0x2b00003) [ 987.206225] pci-stub 0000:09:01.0: PCI INT A disabled [ 987.286791] libvirtd[3193]: segfault at 10 ip 00007f921b4546b4 sp 00007f9216e165e0 error 4 in libpthread-2.10.1.so[7f921b44a000+17000] >From GDB 06:45:32.434: error : qemuMonitorCommandWithHandler:290 : cannot send monitor command 'info cpus': Connection reset by peer 06:45:32.434: error : qemuMonitorTextGetCPUInfo:436 : internal error cannot run monitor command to fetch CPU thread info Program received signal SIGSEGV, Segmentation fault.
