Thank-you for sharing your experience; it will hopefully help by giving
appropriate answers.

Should be fine; may want to try with other technologies in case nothing
else works out, like using Virt Manager for KVM-based VMs, or VirtualBox
for others.

There is no such thing as openSUSE Linux Enterprise 11. I presume you are
running SUSE Linux Enterprise Server (SLES) 11. openSUSE is the name for
the community version of the distribution, and it is currently at version
13.2 so the opensUSE 11.x stuff is really old, where SLES 11 is still

From which DHCP server? If your host SLES system is running one, do you
mean it is running the one that comes with SLES (dhcpd) or the one that
comes from your VMware software? This may be the heart of the problem.

This may be in the range auto-allocated for NAT by VMware. If you do not
want to use VMware's DHCP feature, disable it in your network settings
(assuming possible with VMware Player).

I'm guessing you have two DHCP services, perhaps because you did not know
that VMware setup a DHCP service for you. If it did, then disable it and
your SLES one sounds like it will already work as soon as you get past the
timing issue that makes getting an IP from VMware or from SLES all about
luck of the draw.

You're doing very well despite that.

Good luck.
