Description Cam Mac 2016-08-31 10:22:02 UTC

Description of problem:

When using GUI to import VM, the default tmpdir is /var/tmp. As VMs can be terabytes in size, /var/tmp will likely fill up during unpacking of VM and the process will fail. Could this be made configurable please.

Version-Release number of selected component (if applicable):

4.0.2.7-1.el7.centos

How reproducible:

always

Steps to Reproduce:
1. Upload VM to import domain
2. Select 'import'
3. During conversion process, if the VM exceeds the size of /var/tmp, it will fail

Actual results:

VM import fails

Expected results:

Maybe it would be best to configure this on VDSM side since it can differ from host to host which is the correct tmp dir.

Comment 2 Michal Skrivanek 2016-10-12 13:00:54 UTC

we're rather working on not requiring that much space and convert on the fly, tracking in https://trello.com/c/aNCEeMLV

Comment 3 Tomáš Golembiovský 2017-03-01 15:33:32 UTC

The problem was addressed on virt-v2v level and the fix should be available in RHEL 7.4 time frame. Notably the following components in following versions have to be available:

qemu 2.8.0
libguestfs 1.36.1
libvirt 3.1.0
