Re: [Libguestfs] Virtio-win RPM?



But that export is only in the context of the process where you set it, right?  So if I export LIBGUESTFS_TRACE=1 in a terminal window and then virt-p2v-server starts up in a different process, how does virt-p2v-server get its copy of that global variable?

Here's an experiment - as you can see below, when I export a variable named GREG, another newly created process does not know about it.

[root FedoraP2V ~]#
[root FedoraP2V ~]# export GREG=1
[root FedoraP2V ~]# echo $GREG
1
[root FedoraP2V ~]# ssh -l root 0

[root FedoraP2V ~]# echo $GREG

[root FedoraP2V ~]#


But if I export LIBGUESTFS_TRACE=1 and then start up a copy of virt-p2v-server in the same window by hand, I wonder if this copy will answer the inbound request from the physical machine, or if the migration server will start up another copy?

- Greg

No need for the second line. /usr/bin/virt-p2v-server is started by the p2v client remotely when it connects. All you should need to do on the p2v server is the first line, and then watch the stdout on your screen as the p2v conversion works its magic.
