Hello Pino, I tried installing the package and running the command, however nothing has changed :-/ This package should be installed as an addition to the dhcpcd5 or is a replacement?

When setting up the network, libguestfs tries to use first dhclient if available, then dhcpcd otherwise. I see that libguestfs0 currently in Stretch has a dependency on isc-dhcp-client, but it looks like the version in Jessie does not. Do you have isc-dhcp-client installed on the machine where you run the Python script? If not, install it and then run `libguestfs-test-tool` to update the libguestfs appliance (it will be done anyway later, but this way your script doesn't take more than needed). Once you have done that, does the network work? -- Pino Toscano

Hello Pino, I am still getting the same error however from libguestfs log (when creating VM) seems that DHCP has been found - no 'DHCP can't be found' or whatever error it was. So there is some progress but the issue persists :-/ This is what I have done apt-get purge dhcpcd5* apt-get install isc-dhcp-client echo isc-dhcp-client > /usr/lib/x86_64-linux-gnu/guestfs/supermin.d/zzz-dhcp libguestfs-test-tool (and the message was indeed in the log) So I am wondering what could be the issue. I am enclosing libguestfs log from VM creation http://pastebin.com/A3We5f1F .

To workaround locally, on the host where you are running the libguestfs commands you can do: 1) install isc-dhcp-client 2) as root, `echo isc-dhcp-client > /usr/lib/x86_64-linux-gnu/guestfs/supermin.d/zzz-dhcp` 3) as the user who runs your Python script, run libguestfs-test-tool to update the appliance -- you should see the line: supermin: build: visiting /usr/lib/x86_64-linux-gnu/guestfs/supermin.d/zzz-dhcp type uncompressed packages in its output -- meaning that file was picked correctly (and thus isc-dhcp-client hopefully copied) 4) now the network should work There is a Debian bug about it: https://bugs.debian.org/775514 -- fixed only in Stretch though. Just left a comment there, should be an easy fix for Jessie. Thanks, -- Pino Toscano

Hello Pino, thanks for pointing me to the patched file, it's really working now with this change. Thanks a lot :) Best regards Petr Menšík ________________________________________ From: Pino Toscano <ptoscano(a)redhat.com&gt; Sent: Friday, June 17, 2016 2:23 PM To: libguestfs(a)redhat.com; Mensik, Petr Subject: Re: [Libguestfs] libguestfs can't communicate over network while creating VM On Thursday 16 June 2016 16:28:47 Mensik, Petr wrote: In addition to the dependency issue, dhclient needs the interface as parameter; this has been fixed upstream already, and I left an additional comment in the Debian bug with the patch needed to backport: https://bugs.debian.org/775514#68 You can workaround locally with the following instructions as root: 1) # cd /usr/lib/x86_64-linux-gnu/guestfs/supermin.d/ 2) # tar xzf init.tar.gz 3) patch the 'init' file with the changes in https://github.com/libguestfs/libguestfs/commit/2d2a65504dca732a398d23756... 4) # tar czf init.tar.gz init 5) # rm init Now the network should be working.

Hello Richard, I tried what you have adviced (however zzz-dhcp should be replaced by something else or is that right?) and still nothing changes. Btw dhcpcd should be running on the background or is it fine to have just installed (I tried running script with both options - same result unfortunately). Thanks again.
