"failed to start listening VM" when implementing domain migration on kvm
Last modified: 2009-12-14 16:09:21 EST
Description of problem: I created one domain on kvm and start it. Then, try to migrate the domain to another host(two hosts are all kvm hypervisor, AMD cpus), find that the migration failed with following errors: "error: operation failed: failed to start listening VM" Version-Release number of selected component (if applicable): - libvirt: 0.6.3-11.el5 How reproducible: 100% Steps to Reproduce: 1. virsh define rhel5u3.xml 2. virsh start rhel5u3 3. virsh migrate --live rhel5u3 qemu+ssh://x.x.x.x/system (x.x.x.x is remote ip) Actual results: In step 3, migration failed with following error message: "error: operation failed: failed to start listening VM" Expected results: Migration should succeed on kvm. Additional info: 1, firewall of local & remote is stopped 2, system information: [root@dhcp-66-70-66 ~]# uname -a Linux dhcp-66-70-66.nay.redhat.com 2.6.18-152.el5 #1 SMP Wed Jun 3 18:57:00 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux
Seems the error message comes from kvm actually can you add /var/log/libvirt/qemu/rhel5u3.log from the target machine as an attachment ? Daniel
This can reproduce on [root@dhcp-66-70-82 ~]# uname -a Linux dhcp-66-70-82.nay.redhat.com 2.6.18-155.el5 #1 SMP Fri Jun 19 17:06:31 EDT 2009 x86_64 x86_64 x86_64 GNU/Linux Attached test1.log is /var/log/libvirt/qemu/test1.log from traget machine
Created attachment 349063 [details] /var/log/libvirt/qemu/test1.log
Could you also provide the test1.log from the source machine, and the XML config 'virsh dumpxml test1'
Sorry, the below one test1.log I provided should be log from source machine
Upload target.log which is /var/log/libvirt/qemu/test1.log from traget machine
Created attachment 349070 [details] Log from target machine
Upload test1.xml from '#virsh dumpxml test1'

Here's the important error message from the target: qemu: could not open disk image /var/lib/libvirt/images/test1.img You are trying to migrate a guest whose disk is not accessible on the target machine. You need to storage guest disks on a network'd filesystem or shared/networked block device
Hi, Reopen this bug base on following descriptions: My testing environment is different from the one of yoyzhang@redhat.com. During my migration testing, there is a shared pool ("pool1" below) between local and remote host and the domain ("rhel5u3" below) is located on the shared pool. But the migration (with command "virsh migrate --live rhel5u3 qemu+ssh://x.x.x.x/system", x.x.x.x is remote host ip) failed with the error message "error: operation failed: failed to start listening VM". Following is the config information of local & remote host and you can get the log "/var/log/libvirt/qemu/rhel5u3.log" of local and remote in attachment "rhel5u3local.log" & "rhel5u3remote.log" respectively. === local === /// pool information /// [virsh pool-list] Name State Autostart ----------------------------------------- pool1 active no [root@dhcp-66-70-66 edwang]# virsh pool-dumpxml pool1 <pool type='netfs'> <name>pool1</name> <uuid>3e3fce45-4f53-4fa7-bb32-11f34168b82b</uuid> <capacity>161061273600</capacity> <allocation>87838425088</allocation> <available>73222848512</available> <source> <host name='10.66.71.226'/> <dir path='/vol/libvirt2/manual'/> <format type='auto'/> </source> <target> <path>/var/lib/libvirt/images</path> <permissions> <mode>0700</mode> <owner>0</owner> <group>0</group> </permissions> </target> </pool> /// domain information /// virsh dumpxml rhel5u3 <domain type='kvm' id='4'> <name>rhel5u3</name> <uuid>8f7d7e4c-2c44-49f8-9c59-09b609b00ebd</uuid> <memory>1572864</memory> <currentMemory>1572864</currentMemory> <vcpu>1</vcpu> <os> <type arch='x86_64' machine='pc'>hvm</type> <boot dev='hd'/> </os> <features> <acpi/> <apic/> <pae/> </features> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/libexec/qemu-kvm</emulator> <disk type='file' device='disk'> <source file='/var/lib/libvirt/images/RHEL-Server-5.3-64.qcow2'/> <target dev='hda' bus='ide'/> </disk> <interface type='bridge'> <mac address='0c:07:06:3e:f7:21'/> <source bridge='eth0'/> <target dev='vnet0'/> </interface> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='5900' autoport='yes' keymap='en-us'/> </devices> </domain> === remote === /// pool information /// virsh pool-dumpxml pool1 <pool type='netfs'> <name>pool1</name> <uuid>3e3fce45-4f53-4fa7-bb32-11f34168b82b</uuid> <capacity>161061273600</capacity> <allocation>87838359552</allocation> <available>73222914048</available> <source> <host name='10.66.71.226'/> <dir path='/vol/libvirt2/manual'/> <format type='auto'/> </source> <target> <path>/var/lib/libvirt/images</path> <permissions> <mode>0700</mode> <owner>0</owner> <group>0</group> </permissions> </target> </pool>
