So if you have some control of the routing around that network you simply need to enable ip forwarding and set the routing tables properly. The standard trick with tun devices and UMLs is to bridge them to the external network interface, this way the hosted OS will communicate as if its on the external network, it can take DHCP and do all the rest. Of course if you are on a single machine broadband/dialup connection you WILL need to setup NAT and such since you'll effectively have one gateway machine (the host) and one network client (the hosted).

Quoting Hetz Ben Hamo, from the post of Thu, 27 May: * It's not only emulating full X86 system, but also: * PowerPC (604 for now) * ARM 7 * Sparc (no FPU yet) in other words it works more like bochs than VMWARE and will probably never reach the execution speed of native code, since it's emulating the CPU itself, am I right? VMWARE will always be faster since it allows the X86 opcodes execute on the CPU without translation layers. -- May cause irritation Ira Abramov http://ira.abramov.org/email/ = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]

Actually UML is not that complicated considering the fact that precompiled kernel rpms exist (both for host and for UML machines): http://www.nrh-up2date.org/howto/uml/packages/ Guy On Thu, 2004-05-27 at 18:06, Tzafrir Cohen wrote: On Thu, May 27, 2004 at 04:14:43PM +0200, Uri Sharf wrote: The User Mode sounds interesting, any experiance with that?

Well, there's a script to convert VMWare images to full hard drive image, but it's not stable yet to replace VMWare. Trust me on that ;) Also the network stuff is using SLiRP (or TUN, depends how do you configure it), so it might have some problems ..

Re: Competitor to VMWare?
One exception: You need a modified kernel for the simulated system. Wrong. I've used standard redhat 9 as guest and it worked out of the box without any kernel compilation, not in guest side nor in the host side. Only thing you do need is the ne2k module (which is compiled by default on most distro's if I'm not mistaken)..

Hetz, How hard is to install XP or 2000? special kernel? special modules? I installed XP at work with it without much problems, but there are some emulation problems with QEMU, so remember - it's not finished product. How hard is to run knoppixes from this beast? Runs excellent. Put the CD in driver, Type: qemu -m 256 -cdrom /dev/cdrom -user-net Thats it, it should run ;) Thanks, Hetz = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
Re: Competitor to VMWare?
how about network? was it out of the box? how much setup did you need? Network is seperated into 2 - you can use the TUN support (which frankly, I didn't yet manage to use it) or the SLiRP support (compile QEMU with --enable-slirp and user -user-net when you launch QEMU) With SLiRP, QEMU will have a tiny DHCP server to serve your windows/Linux guest OS which will be good enough for mail/irc/web, but not for ping In both ways, you'll need to do some iptables tricks to connect to your host OS..

Are you sure? tun creates simply another network interface. So if you have some control of the routing around that network you simply need to enable ip forwarding and set the routing tables properly. IIRC there should be a broadcast variant of the tun device (tap?). This should theoretically allow you to configure the host system as an ethernet bridge (that is: like a network switch). So any network config of the host should be transparent. -- Tzafrir Cohen +---+ http://www.technion.ac.il/~tzafrir/ |vim is a mutt's best friend| mailto:[EMAIL PROTECTED] +---+ = To unsubscribe, send mail to [EMAIL PROTECTED] with the word unsubscribe in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
