Not sure we support compressed images, did that scenario used to work in the past? (In reply to Tal Nisan from comment #2) > Not sure we support compressed images, did that scenario used to work in the > past? I don't think it was working in the past. But we provide appliance images like cloudforms in compressed format and have instructions in the documentation to upload those in RHV. A similar issue was fixed in Bug 1470435 using "qemu-img measure". Daniel, what do you think? (In reply to Tal Nisan from comment #4) > Daniel, what do you think? afaik, we don't support it for images chain, i.e. need to support compressed format on images chain. (In reply to Tal Nisan from comment #2) > Not sure we support compressed images, did that scenario used to work in the > past? According to this BZ 1470435 we do support them, since this BZ was fixed with a note implying we support it. Also, based on bz 1470435 comment 15 and others, it seems like there is no such thing as a compressed qcow image. Probably the very same thing here, but using images from glance: BZ1727678 Verified. According those steps: 1. Downloaded from web to a host "CFME 5.11.3 Red Hat Virtual Appliance (qcow)" image from here [1] 2. Uploaded the qcow image to ISCSI sd using upload_disk.py [2] 3. Attach the image/disk to a VM created out of rhel8 template. 4. perform LSM + cold disk migration Actual result: Both migrations succeeded. Both DID NOT fail with the error "No space left on device". Tested on: ovirt-engine-4.4.0-0.25.master.el8ev.noarch vdsm-4.40.5-1.el8ev.x86_64 [1]: https://access.redhat.com/downloads/content/167/ver=5.0/rhel---8/5.0/x86_64/product-software [2]: python3 upload_disk.py cfme-rhevm-5.11.3.1-1.x86_64.qcow2 --engine-url https://storage-ge-09.XXX.XXX --username XXX --disk-format qcow2 --disk-sparse --sd-name iscsi_0 -c /root/ca.pem --insecure https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/upload_disk.py Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
