I'm also seeing some strange behavior on normal qcow2 (local) storage. When it is installing the template to primary storage, in the past it has detected we are going from qcow2 to qcow2 and simply copies the image rather than going the costly route of 'qemu-img convert'. It still does that, but prior to the cp it is creating a new qcow2, then copying over it with the template. So if I had to guess, the LVM might actually work if it didn't try to qemu-img create before doing the regular template copy that is appropriate for the storage type. I think we can skip the "qemu-img create" in this template install code path. 2014-03-27 17:37:35,949 DEBUG [kvm.storage.KVMStorageProcessor] (agentRequest-Handler-3:null) Copying template to primary storage, template format is qcow2 2014-03-27 17:37:35,969 DEBUG [kvm.storage.LibvirtStorageAdaptor] (agentRequest-Handler-3:null) copyPhysicalDisk: disk size:194240512, virtualsize:1073741824 format:qcow2 2014-03-27 17:37:35,969 DEBUG [utils.script.Script] (agentRequest-Handler-3:null) Executing: qemu-img create -o preallocation=off, -f qcow2 /var/lib/libvirt/images/11b71cf8-382f-4b38-a2b0-45e148a010e7 1073741824 2014-03-27 17:37:36,019 DEBUG [utils.script.Script] (agentRequest-Handler-3:null) Execution is successful. 2014-03-27 17:37:36,019 DEBUG [utils.script.Script] (agentRequest-Handler-3:null) Formatting '/var/lib/libvirt/images/11b71cf8-382f-4b38-a2b0-45e148a010e7', fmt=qcow2 size=1073741824 encryption=off cluster_size=65536 preallocation='off' 2014-03-27 17:37:36,020 DEBUG [utils.script.Script] (agentRequest-Handler-3:null) Executing: qemu-img info --output json /var/lib/libvirt/images/11b71cf8-382f-4b38-a2b0-45e148a010e7 2014-03-27 17:37:36,031 DEBUG [utils.script.Script] (agentRequest-Handler-3:null) Execution is successful. 2014-03-27 17:37:36,032 DEBUG [utils.script.Script] (agentRequest-Handler-3:null) Executing: qemu-img info --output json /mnt/939559aa-1bac-310a-a2ce-205336bdb136/2d7d88a8-6233-3ce1-9292-bc805d2e92e5.qcow2 2014-03-27 17:37:36,040 DEBUG [utils.script.Script] (agentRequest-Handler-3:null) Execution is successful. 2014-03-27 17:37:36,041 DEBUG [utils.script.Script] (agentRequest-Handler-3:null) Executing: /bin/bash -c cp -f /mnt/939559aa-1bac-310a-a2ce-205336bdb136/2d7d88a8-6233-3ce1-9292-bc805d2e92e5.qcow2 /var/lib/libvirt/images/11b71cf8-382f-4b38-a2b0-45e148a010e7 - Marcus Sorensen On March 26, 2014, 11:24 p.m., Yoshikazu Nojima wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
