[libvirt-users] live migration not working correctly
by Daniel Bidwell 24 Feb '10

24 Feb '10

I have two servers running Ubuntu 9.10, with shared disk from ISCSI SAN and OCFS2, identical network configurations, shared ssh keys, and pki keys. My vm will boot from either machine and run correctly. When I attempt to do a live migration with "migrate --live base32 qemu +[ssh/tcp]://vm1/system" it initiates the vm on the other server, but leaves the vm on the current server in the "running" state and the vm on the other server in the "paused" state. It never finishes the migration. I get the same results for doing a migration via ssh as I do with tcp/pki. I have turned up the logging to debug, but don't see anything in the log to indicate an error or any reason for it to not complete. At least not anything obvious. The Ubuntu server software is using kvm/qemu version 84. I have been through the ubuntu and qemu forums/wiki/documentation. Anyone have any suggestions of other things to look for? -- Daniel R.

[libvirt-users] Digium TDM410 passthrought to KVM VM trixbox
by raincatsdogs＠me.com 19 Feb '10

19 Feb '10

Hello, my name is Paul. I need to map a PCI device for a virtual machine. The Linux distribution is Ubuntu server 9.10, infrastructure virtualization is "KVM". The virtual machine will install trixbox. To map the PCI card is a "Digium TDM410p. There currently, KVM hosts a virtual machine that runs smoothly without any problems. In fact, this virtual machine is running Openfiler and has direct access to 2 physical disks installed on the server. Creating a new virtual machine can not connect the Digium card, directly to the virtual machine.I tried in 2 ways. 1. Directly editing the XML file for the virtual machine with the parameters indicated in the documentation: ... <devices> <hostdev mode='subsystem' type='pci'> <source> <address bus='0x01' slot='0x00' function='0x0'/> <----- this is my personal configuration </ source> </ hostdev> </ devices> ... 2. Adding the PCI card via virt-manager In both cases, the virtual machine will not start. Virt-manager returns this error: "Error starting domain/ monitor socket did not show up./ Connection refused" "Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/engine.py", line 493, in run_domain vm.startup() File "/usr/share/virt-manager/virtManager/domain.py", line 558, in startup self.vm.create() File "/usr/lib/python2.6/dist-packages/libvirt.py", line 293, in create if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self) libvirtError: monitor socket did not show up.: Connection refused" Can someone kindly help me? Thanks

[libvirt-users] problem with dependencies
by monitz 15 Feb '10

hello i have been having trouble installing libvirt i installed kvm-kmod on rhel 5.4 kernel 2.6.18 without issues using an rpm from the redhat website after installation i tested it by creating an img file with qemu image and went ahead to install libvirt and libvirt-python for virtmanager however during installation of libvirt i get the following error: failed dependencies /usr/bin/qemu-img since qemu-img is in /usr/local/kvm/bin on my system i tried adding it to $PATH, symlinking the file and even copying the binery to /usr/bin but to no use compilation from source seemed to go fine but after that libvirt-python could still not find libvirt is there any solution to this issue? , i would imagine it is a known one thanks in advance matan

[libvirt-users] pre/post vm start commands
by Soeren Grunewald 13 Feb '10

13 Feb '10

Hi there, for development i use a windows vm. which is installed into a disk image. because the compiler generates a lot of temporary files into the user tempdir (C:\\Documents And Users\\User\\Local Settings\\Temp) the vm becomes quite slow after a couple of weeks and i register a lot activity on the disk. so i moved the temp directory to a ram disk and no more problems. but because the ram disk is not formated on startup i need to do this by hand. so i disabled autostart for the vm and do the following: $ sudo mkfs.ntfs -q -L TEMP -I /dev/ram0 $ sudo virsh start windows so the question is, does libvirt provide some kind of pre startup script which is will be executed before the libvirtd does the autostart for the vm. -- Best Regards Soeren

[libvirt-users] error: unable to connect to libvirtd at 'a.b.c.d': Connection refused
by antonela_other＠yahoo.com 12 Feb '10

Greetings: I have an issue with connecting to the esx hypervisor from my guest Vm. The purpose of the connection is to obtain host related information (like network, devices etc). I am not sure what is it that rejects the connect at the server side, and what i am missing. I am running lib0.7.5, i have libvirtd running on guest-vm. The host ESX has the ip address a.b.c.d. Any thoughts? Below the error with some debug output from libvirt. root > virsh -c esx://a.b.c.d/system ...................... 17:06:16.065: debug : virConnectOpenAuth:1337 : name=esx://10.59.56.109/system, auth=0xb80ac638, flags=0 17:06:16.065: debug : do_open:1106 : name "esx://10.59.56.109/system" to URI components: scheme esx opaque (null) authority (null) server 10.59.56.109 user (null) port 0 path /system 17:06:16.065: debug : do_open:1116 : trying driver 0 (Test) ... 17:06:16.066: debug : do_open:1122 : driver 0 Test returned DECLINED 17:06:16.066: debug : do_open:1116 : trying driver 1 (Xen) ... 17:06:16.066: debug : do_open:1122 : driver 1 Xen returned DECLINED 17:06:16.066: debug : do_open:1116 : trying driver 2 (OPENVZ) ... 17:06:16.066: debug : do_open:1122 : driver 2 OPENVZ returned DECLINED 17:06:16.066: debug : do_open:1116 : trying driver 3 (VBOX) ... 17:06:16.066: debug : do_open:1122 : driver 3 VBOX returned DECLINED 17:06:16.066: debug : do_open:1116 : trying driver 4 (remote) ... 17:06:16.067: debug : doRemoteOpen:564 : proceeding with name = esx:///system 17:06:16.069: debug : initialise_gnutls:1145 : loading CA file /etc/pki/CA/cacert.pem 17:06:16.070: debug : initialise_gnutls:1158 : loading client cert and key from files /etc/pki/libvirt/clientcert.pem and /etc/pki/libvirt/private/clientkey.pem 17:06:16.074: debug : do_open:1122 : driver 4 remote returned ERROR 17:06:16.074: debug : virUnrefConnect:259 : unref connection 0x903e078 1 17:06:16.074: debug : virReleaseConnect:216 : release connection 0x903e078 error: unable to connect to libvirtd at a.b.c.d': Connection refused error: failed to connect to the hypervisor I tried to use uri like: esx://a.b.c.d/, esx://a.b.c.d, esxi://a.b.c.d/system etc. They all give same issue.

[libvirt-users] libvirt attaching wrong usb device?
by Tom Hughes 11 Feb '10

11 Feb '10

I'm trying to attach a USB device which is attached to my host to a guest instance. The device definition in the XML looks like: <hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x046d'/> <product id='0xc111'/> </source> </hostdev> and the device appears in lsusb as USB device 002:018: Bus 002 Device 018: ID 046d:c111 Logitech, Inc. but when I try and start the guest libvirt appears to try and use a different device which doesn't exist: error: unable to set security context '107:107' on '/dev/bus/usb/002/022': No such file or directory This is using the current libvirt-0.7.6-1.fc12.x86_64 package from the F12 virt-preview repository.
