Subject: running linux in vm on linux box


Hi Mike!

 MP> I have a few questions about running a linux distro in a vm on a
 MP> linux box.  I have read up about how to get Ethernet working over
 MP> a bridge, but have not yet got to installing the system, etc.

As not too many people doing this here I'll attempt some answers.  I'm 
currently running Windows XP on a Virtual Machine; no exerience (yet!)
with a virtual Linux on a Linux -- planning on that with the next 
machine.

S.N. - sort of just to further confuse us, there are at least two 
virtual machine options out there.  The one I am using is from Oracle; 
the one available through the Software Centre isn't as robust.


 MP> (1) When the qemu session is running, is it smart to use the
 MP> xserver on the vm instance?  If I am not using the xserver and
 MP> running the vm instance in consolemode, will qemu catch certain
 MP> keystrokes like ctrl-alt-2 so I can switch totty2 (for example)
 MP> or will that keystroke combo be interpreted by the hostmachine?

Not sure -- different system here but I have not had problems with the 
keyboard nor mouse switching between multiple OSs/sessions as long as 
they are set for 'shared' and not 'exclusive' or whatever the 
terminology is.


 MP> (2) If I can follow the directions and get the Ethernet bride
 MP> working correctly, so that the network can see both the host and
 MP> vm, I assume I can also do things like mount nfs shares in the
 MP> vm.  Is that a correct assumption?

Here the one Ethernet cable sees both 192.168.0.21 for the main Linux 
system and 10.2.0.15 for the virtual Windows XP system concurrently.  
You can create shared folders which see certain parts of the mounted 
drives.  Possibly the whole drive if configured that way -- I didn't
need and didn't want here so didn't do it that way.


 MP> (3) Will I be able to access other hardware while in the vm, like
 MP> a usb port and whatever might be connected to it?

Yes but you will want to download the optional Guest Additions software 
else you will only have USB 1.0 with the Oracle VM machine.

The USB hardware portion is a little strange. though may be because I 
screwed up some configuration a while back and never fixed it because 
I'm goingto move to a New and Improved machine (but first!).  Here the 
scanner is always grabbed by the VM -- just unclick while the VM is 
loading.  A digital camera I play with is never loaded unless I 
specifically click, nor is a thumbdrive I use as a transfer point.  No 
idea why some USB devices are grabbed by the VM and others are not; just
something one needs to look at when plugging in a device and it "doens't
work": does the other machine have it?


 MP> I have run DOS in a vm on a linux box, but I expect this to be
 MP> different.  :)

(Oops! I probably should have read all the way through!)  I predict you 
will be giving your scalp a masssge during installation!
