Alexander is correct in saying that bridging would allow you to do that. There are two networking discussed in the guide. The first is a NAT (network address translation), in which the guests are given "private" ip addresses and any outbound traffic appears to be coming from the host machine's IP address. This is the same as the setup on your ADSL router where the internal network machines get addresses of 192.168.x.x but the internet sees your requests as coming from the IP address of your router. There should be lots of documentation in linux firewalling guides under sections on NAT (or possibly called IP Masquerading in some). Have a look at these for information on port forwarding to reveal services inside the virtual (such as ssh). The other option is bridging. This shares the physical network interface of the host with the guest. In this case the VM acts as though it's a machine plugged into the same subnet as the host, its services are accessible like those of the host and it's as vulnerable to attack as the host. Robert

Need Pointers for Setting up Virt Host + Guests
by Frank Murphy 29 Jun '10

29 Jun '10

Have a box with a 320GB and a 500gm sata hds' What is the best method to set this up. It's a core 2 quad 64bit, with currently 4gb ram (max 8) I would like it to run Fedora12 32+64 && Fedora13 32+64 && Rawhide. For trying to reproduce certain bugs on current Releases. I can add extra drives to box as necessary. Best base F12,F13, Rawhide? XFCE is my preferred DE. -- Regards, Frank Murphy UTF_8 Encoded Friend of Fedora

pxe boot again
by Farkas Levente 21 Jun '10

21 Jun '10

hi, i already wrote a thread about it a long time ago: https://www.redhat.com/archives/et-mgmt-tools/2008-May/msg00139.html now i try it again. we've got a working pxe server and use it to install all of our system. now i like to test it, but it still (or again) not working. with virtualbox 3.2 if i choose bridged networking and switch off VT-x/AMD-V support as described in: http://www.virtualbox.org/ticket/2536 than it's working. but with kvm not. so is there anybody who can tell me: - is the pxe boot working in virt-manager kvm? - if yes, which kind of setup? ie: - which kind of networking to choose? - nat or bridged? - what else should i've to configure to get it working? thanks in advance. regards. -- Levente "Si vis pacem para bellum!"

boot.fedoraproject.org?
by Tom Horsley 20 Jun '10

20 Jun '10

I'm experimenting with boot.fedoraproject.org again, trying to install a KVM booted from the bfo.iso boot CD image, and I'm noticing some wacky behavior. When I let the image file boot normally the DHCP step always prints dots for several seconds then fails. If I send a Ctrl-Alt-Del to the KVM after the initial network failure, it reboots and the 2nd DHCP attempt prints one dot then immediately says "Here we go!" (There was a mention of this same behavior for PXE here: http://lists.fedoraproject.org/pipermail/virt/2010-June/002108.html and the Ctrl-Alt-Del thing worked for gPXE as well). I'm now trying to install f13, and it is downloading the install.img file. Looking at my network stats, it is only managing a data rate of about 15K (occasionally hitting a peak of 20K). Meanwhile, the cpu is running at 99%. Is the gPXE ethernet running one byte at a time polled transfers or something? I'll see if the transfer rate improves once it starts running the anaconda kernel (but it may take a while to get that far :-).

Re: [fedora-virt] Losing sound in Win XP qemu-kvm guest
by jah 16 Jun '10

Thanks for the reply Gilboa. I had given up on getting a response to my email and almost didn't spot it. It's disappointing that nobody from Red Hat feels like it's worth responding to. The only thing I could find in Bugzilla was 520228, a very similar problem with F11 from Aug 2009. Though this pertains to my Fedora desktop at home, possibly my Red Hat rep at work can find a resource who would share some insight on the problem. Anyway, I switched QEMU_AUDIO_DRV from "alsa" to "pa" and that made the problem worse, sound went out a few minutes after starting the guest. I don't have any experience running KVM under F12 but I am running Virtualbox under F12 at work (no hardware virtual extentions) and sound works great in my XP guest. What exactly are the "connection refused" messages you're getting from qemu? The only unusual messages I'm getting are occasional bursts of this message: Jun 11 23:52:51 host pulseaudio[2651]: ratelimit.c: 676 events suppressed Jun 12 10:10:06 host pulseaudio[2651]: ratelimit.c: 676 events suppressed Jun 12 11:02:53 host pulseaudio[2651]: ratelimit.c: 685 events suppressed In Gentoo I only had this problem when I ran KVM as a module, not when it was compiled into the kernel. Unfortunately nowdays compiling a custom kernel in Red Hat/Fedora is a little more involved and not really worth re-doing every time a new kernel update comes out. -jah > Seeing the same. > My script defaults to PA. > > Looking at the console, I see that qemu is getting connection refused. > I'd imagine that the problem is that my scripts runs as root (I use only > bridged networks), and PA (per-user) is getting rejected. > > What I don't understand is - why it worked just fine under F12, and why > it doesn't work now?

Is the Stable PCI Address feature in Fedora 13 supposed to fix the problem of Windows 7 guests detecting a new network interface at each boot? Adam

Fedora 13 and Win XP Guest - Boot anomaly
by Ken Smith 14 Jun '10

14 Jun '10

Hi, New to the list but not to Linux. There has been a discussion on the "Fedora Users" list about an anomaly that's been seen with FC13 64bit and installing XP as a guest. It's a standard FC13 installation on a machine with an Intel i7 and 4G Ram. When the XP installation finishes the initial text style part of its install process and reboots to run the GUI part of the install process the virtual machine fails to boot it from the virtualised hard disk. But if its set to boot from the CD or, in my case, the iso image of a XP install CD and its allowed to time out its initial question "Press any key to boot from CD....." then the virtual machine starts up and completes the XP installation. One the installation is finished, similar behaviour is seen to get the XP virtual system to start up. If I change the setting in virt-manager to boot from the Hard Disk image the boot of the VM fails but leaving it set to boot from the install CD allows it to start normally after allowing the initial question to timeout I have cc'd Suvayu Ali on this posting as he has also observed similar behaviour. The thread on the Fedora Users list is here -> http://lists.fedoraproject.org/pipermail/users/2010-June/374730.html Any suggestions. Thanks Ken -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
