Sorry richard
seems that it failed even when i tried to set that variable
Maybe i set up the command incorrectly?
here is what i ran
[root@server3 ~]# cat convrtesxhost.sh
#!/bin/bash
export LIBGUESTFS_TRACE=1 export LIBGUESTFS_DEBUG=1 export LIBGUESTFS_BACKEND=direct
virt-v2v -ic esx://ESX.decllc.biz/?no_verify=1 -o rhev -os server3.decllc.biz:/localstorage/nfs --network ovirtmgmt razDC 2>&1 | tee /var/log/virt-v2v.log
It looks like this is correctly setting the environment variable:
[root@server3 ~]# ./convrtesxhost.sh virt-v2v: Transferring storage volume razDC_razDC: 107374182400 bytes libguestfs: trace: set_verbose true libguestfs: trace: set_verbose = 0 libguestfs: trace: set_backend "direct" libguestfs: trace: set_backend = 0
^ see that it's set correctly here. [...]

So this is not the bug I was thinking of. (In fact it's obvious now I look closer. This has nothing to do with libvirt, and the error message is being generated by libguestfs earlier on) Is there some other reason that libguestfs would not be able to open that file in /tmp? Perhaps there is an SELinux AVC? Or /tmp has strange permissions ...? Is /tmp a tmpfs mount? I believe the actual code path you're hitting is this one: https://github.com/libguestfs/libguestfs/blob/stable-1.22/src/drives.c#L660 I'm not exactly sure why that fails.
