Howto connect to a terminal in an emalated linux-livecd?
Hi list, after hours for searching in google-world, i didnt find any appropriate for this problem: I want to boot a live-cd (i.e. ubuntu 14.04.1-desktop) in qemu, which starts with an graphical interface, done i.e. by qemu-system-x86_64 -m 3G -smp 2 -drive file=ubuntu-14.04.1-desktop-i386.iso,media=cdrom,if=virtio --enable-kvm Now i want to access to the console of the ubuntu-livecd. At the moment i can do this over changing to text mode via sendkey ctrl-alt-f1 in qemu-console (Alt-2), then switching back to qemu-window (alt-1). Now i have access to tty1 of my livecd. But IMHO there should be a more simple way to access to such a console with qemu, i.e. through a pipe, a serial console etc., but i didnt found anything working. The best i got was with -chardev pty,id=myid, which resulted in a char device redirected to /dev/pts/0 (label myid). But with a screen /dev/pts/0 i wasnt able to see any input or output. ssh is unfortunatly not available at this time on the livecd (so i could connect i.e. via -net user,hostfwd:tcp:10022-:22) Any hints to connect directly to a console in an emulated linux?

Re: lightscribe support
Hi Nerijus, Am 14.02.2014 22:29, schrieb Nerijus Baliunas: Hello, is it possible to support lightscribe in KVM? Now Windows VM sees QEMU DVD-ROM ATA Device and labeling software shows No LightScribe Drives Found. Normally kvm emulates the cdrom drive. If you want to use the native functionality, you have to passthrough the drive (depending on the your device usb or pci sata-hardware). If your drive is attached via usb, you can try passthrough the usb-device, if it is connected via sata, you have to passthrough the sata-pci-device.

SOLVED [was Re: Controlling (WinXP-Guest)- Textmode via chardev pipe broken?]

You're not emulating a keyboard there, you're emulating input from a serial device. HI Sasha, Ive found a better solution: It is possible to pipe the qemu-monitor: qemu ... -monitor pipe:.winpipe/path so Im able to send commands through the path.in pipe via sendkey-kommand, i.e. echo sendkey r .winpipe/path.in echo sendkey d .winpipe/path.in echo sendkey shift-dot .winpipe/path.in echo sendkey ret .winpipe/path.in Its not very komfortable, but does its job :-) Tfh!

Controlling (WinXP-Guest)- Textmode via chardev pipe broken?
Hi List,
Im trying to control a winxp installation process (esp. the text-mode
part) via pipe through kvm. Im using the git-version of kvm from
yesterday (2011-12-19), build with these parameters:
~/qemu-kvm$ ./configure --enable-sdl
~/qemu-kvm$ make
~/qemu-kvm$ sudo make install
What works:
1. Generating ~/.winpipe/path.{in,out}via mkdir .winpipe; mkfifo
.winpipe/path.in; mkfifo .winpipe/path.out
2. Creating emty image via qemu-img create win.img 20G
3. Starting kvm via: qemu-system-x86_64 -m 1G -hda win.img -cdrom
winxpsp3.iso -chardev pipe,id=mywinpipe,path=.winpipe/path
What doesn't:
1. Piping some text via echo R .winpipe/path.in (i.e. for starting
repair console in winxp-textmode) doesnt have any effect
2. Reading from path.out via cat ~/.winpipe/path.out (nothing happens
except the vm ends, then the command cat .winpipe/path.out ends, too)
has no result, only waiting
3. There is no .pipe/ directory inside winxp, wether on C: nor on D:
(looked in via starting repair-console with R)
Whats wrong?
Tfh!
Oliver

setting motherboard serial number?
Hi list, i have a little problem: a program of us is looking for the serial number of the motherboard via dmidecode -s baseboard-serial-number which returns normally (i.e. Athlon Board) a 16-digits-number. But doing this in a virtualized (i.e. Ubuntu-oneric-11.10) box, the command returns the empty string. Is there any possibility to set this number when defining the virtual machine? Tfh!

faking vendor-id to guest for driver-install-triggering?
Hi there, is it possible to announce the kvm-guest (i.e. winxp) some arbitrary vendor-id's in a way, that the win-client starts to install the driver for this card? I.e. the RTL8111/8168B PCI Express Gigabit Ethernet Card has the vendor-id 10ec:8168 (taken from lspci -nn), so if i give this ID to the kvm-guest, he should install the driver for this card. Tfh!

OT: Intel-Matrix for VT-capability?
Hi, Im looking for an abillity seeing vt-capability of Intel-processors by there name :-/ I.e. T7200 has vt, T3400 has not. Exists a rule for the naming scheme seeing vt-capability? Alternatively, exists a matrix anywhere in the net for this? Im tired searching for vt-capability for every new OEM-intel-processor. On intel-site _did_ exist a pdf-table (not all processors, but most of T-series), but it seems to be removed.

Re: KVM on Via Nano (Isaiah) CPUs?
Hi Jesse! Jesse Ahrens schrieb: Via engineers have contacted me and confirmed that this is a problem in the processor. I'd like to clarify. Stepping 2 Nano processors do not support VMX. This should have been disabled by the BIOS. Support for VMX was not finished until stepping 3. If you have a stepping 2 processor with this enabled please let me know which platform it is on so we can have the manufacturer release a new BIOS. What is the actual Stepping for Via Nano Processors? Is VT running fine since stepping 3?

Name kvm ambiguos
Hi List, it is interesting, that most people at name kvm first think for vga-hardware switches. If you type kvm in google, you'll never find this project at the first place. Maybe (i know thats difficult to realize) it is better looking for another name? Like kevim? Its only a suggestion...

Single Graphic Card only for KVM-Guest, not Linux?
Hi, what must I do assigning a graphic card pci-device to (i.e. winXP-client) guest? In my case, the vga-adapter uses irq 16, so that I think, it could be possible to mask out this irq, so that it is free for using in the guest. Im deactivating _lots_ of linux-options so linux ist not using the graphics adapter anymore, but no access. Is it usefull to disable msi-reassigning? Always i get the failure: pci :00:02.0: power state changed by ACPI to D0 pci :00:02.0: PCI INT A - GSI 16 (level, low) - IRQ 16 kvm: failed to enable MSI device! kvm: failed to enable INTx device! pci :00:02.0: PCI INT A disabled kvm: emulating exchange as write What can i do?

network source redirection after kvm start
Hi, Im new to this group, so let me know if i do something wrong.
