[uml-user] Set terminal background color

Hi everybody,
I am invoking my UML instances from an rxvt terminal window with black
background and white foreground color. For some weird reason the
terminal window that pops up with the UML login prompt is inverted -
white background and black text color.
I've no idea where to change this. What is really weird is that I moved
my UML images from one host (running Debian) to another (running Ubuntu)
 - this color inversion only appears on the latter one. Does anybody
have a clue where to change terminal window background colors?

(When calling rxvt one can pass the colors to rxvt as arguments. But UML
opens another terminal window with different colors...)

Currently, I start my UML instances that way:
./linux mem=64M ubd0=./umlmaster.img ubd1=./swapmaster.img con=pty
con0=fd:0,fd:1 con1=xterm eth0=tuntap,tap0

Any help is appreciated, thanks very much in advance!

[uml-user] Moving from UML to standalone

RE: [uml-user] Moving from UML to standalone

I'd think it was possible to use dd to copy the file that contains the UML
root_fs to a physical hard drive, but you would need to have physical access
to the machine at the ISP, which is probably not a possibility. Maybe have
them burn a DVD of it?

Subject: [uml-user] Moving from UML to standalone

Hiya,
 
This might be a really, really stupid question, but I'm not in-tune with
what UML really does so please excuse if so.
 
I'm on an UML server via my ISP, but thinking of moving to either a new
virtual hosting service or a standalone machine.
Is it possilbe to do an image of my UML installation and extract it on a
physical harddrive, and getting it to boot?
 
I fear I can simply forget this but it would be really nice since I've got a
pretty complex system setup.
 
Regards,
Daniel

A uml file system is most normally an ext3 (or some other fs) image
plus a cow file (for local writes). You could just export the
filesystem.

Alternately, standard backup tools would do the job.

Use tar if it's going to a physical disk.  In this case, you'll need
to fix device names in fstab, inittab, and securetty, and make sure
that grub/lilo are set up correctly.

If it's going to another UML host, then just copy the filesystem image
(and COW image, if applicable) over.

Depending on your Linux flavor (Fedora, Debian, etc.), it may help to  
pre-install some packages that a UML instance doesn't need. For  
example, you may need to install the software for grub (or lilo), the  
kernel (with kernel modules), etc.

Also, I've used tar for backing up (and restoring) instances. It works  
quite well. Just remember use your boot-loader (grub, lilo, etc) to  
reinstall the boot block when you move it to its own hardware.

Also, it wouldn't hurt to have a rescue disk pre-built so you have a  
known, working means for booting the instance.

Good luck!

Tony

Uml is using xterm, you'd want it to use rxvt. You can do it by passing the 
additional switch:
xterm=$(which rxvt)

Refer to ./linux --help looking for xterm for additional details.

Re: [uml-user] Where is the latest skas patch?

Oh, sorry. I eventually did the whole patch/build procedure directly on
the target (skas) machine (FC5 with gcc 4.1.0) and both the host and the
uml guest worked ok. This machine is different then my dev machine
(ubuntu 6.0.6 with gcc 4.0.3) where the rebooting kernel was compiled.

[uml-user] UML book review on Slashdot

Good afternoon, all,
 	Ravi Kumar just posted a review of Jeff's UML book on Slashdot:

http://books.slashdot.org/article.pl?sid=06/06/05/169212

 	In inimitable Slashdot fashion, the comments currently are a 
discussion of whether UML should stand for User-Mode Linux or Unified 
Modeling Language.  *sigh*  That said, the review looks good.
 	Does everyone have their copy yet?  *smile*
 	Cheers,
 	- Bill
