Re: [ovirt-users] Import KVM/libvirt VMs to oVirt 4.1 with External Provider
Hi Team, While importing VMs with external Provider KVM on my oVirt setup, i am getting the below error: "All chosen VMs couldn't be retrieved by the external system and therefore have been filtered. Please see log for details. As per Shahar suggestion yesterday i was able to view the virtual machine of my KVM hypervisior in oVirt Portal.I have also created the export domain in my DC as well. Any idea how to resolve this issue and so that i can start importing VMs [image: Inline image 1] Thanks in Advance On Wed, Mar 29, 2017 at 6:17 PM, Pradeep Antil <pradeepantil@gmail.com> wrote:

Sorry for the miss leading message, its suppose to say that some of the selected VMs cannot be imported. This can be due to broken storage disk path or any other Libvirt parsing error. For more details you can look at the vdsm log (/var/log/vdsm/vdsm.log) and see why we failed to parse Libvirt xml for each VM that is not in the right list.

Hi Shahar , vdsm shows the following errors. Just giving the background how do we created VMs in KVM, All the VMs are created on separate Luns of 100 GB and before creating VMs in KVM we usually format the LUN and then we create VMs on the formatted Lun.In this case we have mount the formatted Lun under "/opt/wiki-uat". I am just curious to know , will this type of VMs can be imported in Ovirt. 2017-03-30 12:30:17,999+0530 INFO (jsonrpc/7) [jsonrpc.JsonRpcServer] RPC call Host.getStats succeeded in 0.02 seconds (__init__:515) 2017-03-30 12:30:19,366+0530 INFO (jsonrpc/4) [throttled] Current getAllVmStats: {} (throttledlog:105) 2017-03-30 12:30:19,367+0530 INFO (jsonrpc/4) [jsonrpc.JsonRpcServer] RPC call Host.getAllVmStats succeeded in 0.00 seconds (__init__:515) 2017-03-30 12:30:20,028+0530 ERROR (jsonrpc/6) [root] Error getting disk size (v2v:1084) Traceback (most recent call last): File "/usr/lib/python2.7/site-packages/vdsm/v2v.py", line 1073, in _get_disk_info vol = conn.storageVolLookupByPath(disk['alias']) File "/usr/lib64/python2.7/site-packages/libvirt.py", line 4770, in storageVolLookupByPath if ret is None:raise libvirtError('virStorageVolLookupByPath() failed', conn=self) libvirtError: Storage volume not found: no storage vol with matching path 2017-03-30 12:30:20,029+0530 WARN (jsonrpc/6) [root] Cannot add VM wiki-uat due to disk storage error (v2v:1015) 2017-03-30 12:30:20,034+0530 INFO (jsonrpc/6) [jsonrpc.JsonRpcServer] RPC call Host.getExternalVMs succeeded in 0.48 seconds (__init__:515) Below are the contents of VM libvirt xml file <uuid>9e2f7338-9f13-32db-ea50-d6d9467e1345</uuid> <memory unit='KiB'>2097152</memory> <currentMemory unit='KiB'>2097152</currentMemory> <vcpu placement='static'>2</vcpu> <os> <type arch='x86_64' machine='rhel6.5.0'>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'> <driver name='qemu' type='raw' cache='none'/> <source file='/opt/wiki-uat/mediawiki-uat.img'/> <target dev='hda' bus='ide'/> <address type='drive' controller='0' bus='0' target='0' unit='0'/> </disk> <controller type='usb' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x2'/> </controller> <controller type='ide' index='0'> <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x1'/> </controller> <interface type='bridge'> <mac address='52:54:00:0a:fb:e2'/> <source bridge='br10'/> <model type='e1000'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> <serial type='pty'> <target port='0'/> </serial> <console type='pty'> <target type='serial' port='0'/> </console> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes'/> <sound model='ich6'> <address type='pci' domain='0x0000' bus='0x00' slot='0x04' function='0x0'/> </sound> <video> <model type='cirrus' vram='9216' heads='1'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x02' function='0x0'/> </video> <memballoon model='virtio'> <address type='pci' domain='0x0000' bus='0x00' slot='0x05' function='0x0'/> </memballoon> </devices> On Thu, Mar 30, 2017 at 12:16 PM, Shahar Havivi <shavivi@redhat.com> wrote:

When we try to do: vol = conn.storageVolLookupByPath(disk['alias']) e.g: vol = conn.storageVolLookupByPath('/opt/wiki-uat/mediawiki-uat.img') Libvirt raise an error: "libvirtError: Storage volume not found: no storage vol with matching path" e.g.: '/opt/wiki-uat/mediawiki-uat.img' is not exists Please look if the path exists (via the host that the Libvirt Domains exists).
