I think I found the issue.
The /etc/init.d/vmcontext script contains these lines:
if [ -e "/dev/disk/by-label/CONTEXT" ]; then
mount -t iso9660 -L CONTEXT -o ro /mnt
..I changed these to:
if [ -e "/dev/disk/by-label/CDROM" ]; then
mount -t iso9660 -L CDROM -o ro /mnt
..after investigating the /dev/disk/by-label directory, and seeing that the
context emulated CD had that label. It seems to work now, but I have one more
issue – I need serach domains to be included in the resolv.conf. I have defined
them in the virtual network template, but they don’t seem to be making it into
the resolv.conf on boot. I guess I can work this out by poring over the context
scripts some more… ☺
Please let me know if there’s anywhere I should be looking…
Thanks
Jerry

This happened to me when I imported a CentOS image from the marketplace. It had
one-context 3.8 installed, but I was running opennebula 4.2.
It seems there's a difference in the way network context variables were passed
between those versions, so updating one-context in the VM might fix it for you.

...in fact, some further investigation shows that the network context variables

just putting the defaults in there, rather than the variables I've specified
(so, e.g. for the gateway, take the first three quads of the network address,
and put a ".1" after it, or the default netmask is "255.255.255.0").
Anyone know why *this* might be happening?
Thanks

Hi Javier,
The output of "onevm show <network id>" does give the correct information,
however, I have noticed that in the CONTEXT=[] statement, I have the variable
ETH0_NETWORK set to "10.54.136.0", and looking at the context script in the
(Debian) VM - /etc/one-context.d/00-network - it seems to take that and use it
to generate netmask and default gateway from the VM, thus ending up with the
both an incorrect netmask, and an incorrect gateway.
Why would this be happening?
Thanks
Jerry

Are you getting correct data in your deployed VM? That is, that in the output
of "onevm show <vmid>" the context section has the values it is supposed to
have.
