Hmmm... one of my VMware machines defaulted to 64bit with
e1000g as the default adapter. Is this normal behavior
on a 64bit host perhaps? (2x dual core opterons and 8G
of memory running XP x64 edition).
I don't have a 32bit machine handy to check it out... :P
bill.

Is anyone here seeing the following problem, too ?
I am getting very bad network performance with VMware 5.5.1 build 19175
and Solaris Express B37 (directly installed from DVD). The network
performance is very low, sometimes <= 20kb/s (or lower) and sometimes
packages get lost.
In another VM runs Solaris 10 Update 1 perfectly so I assume this is a
bug in Solaris Express B37...
What ethernet device is being used? I've had similar symptoms until I changed
from pcn to e1000g (ethernet0.virtualDev = "e1000" in .vmx file, AFAIR)
"pcn0" was the device in Solaris (from /var/adm/messages

) - and switching to "e1000g" fixed the problem. Thank you very much...
:-)
For the log:
The full sequence to get the ethernet card "switched" in Solaris (from
"pcn0" to "e1000g") looks like this:
1. In the Vmware VM guest (Solaris:
% mv /etc/hostname.pcn0 /etc/hostname.e1000g0
% touch /reconfigure
% sync ; sync # yes, yes, I am paranoid
% init 0
2. Turn guest OS off after it has completed it's shutdown
3. Locate the *.vmx file which belongs to the Solaris Express VM
4. Make a copy of the ".vmx" file
% cp sxexb37001.vmx sxexb37001.vmx_backup20060523
5. Edit it and add the following line:
-- snip --
ethernet0.virtualDev = "e1000"
-- snip --
6. Restart the VM (this may need to be done twice for unknown reasons...
;-( )
Result:
"scp" now copies files with more than 4.3MB/s from host OS to the
Solaris Express B37 client... :-)
BTW: Why isn't the "e1000g" the default for Solaris guest OSes ? Are
there any problems with the "e1000g" emulation ?
To Nolan: Can you file a small RFE in the VMware bug DB to add a GUI
dropdown that people can select between both the "pcn" and "e1000g"
network card emulations, please ? This may be a quick solution in such
cases and would avoid that people have to hack the *.vmx config file
manually...
