Software :: Qemu Booting From CD Won't Reboot From CD
May 17, 2011
After I boot from a CD rom in QEMU, trying to reboot within the virtual machine (e.g. doing the "reboot" command at the root shell on Linux running inside), fails. The OS goes through the motions and the virtual machine starts to reboot. But then it cannot get to the CD the 2nd time around. The message I see in QEMU is:
Code:
Starting SeaBIOS (version pre-0.6.1-20100902_143500-palmer)
Booting from CD-Rom...
Boot failed: Could not read from CDROM (code 0003)
No bootable device.
The qemu command I'm running is:
Code:
qemu-system-x86_64 -alt-grab -hda hda.img -cdrom cda.iso -m 1024 -boot d -net nic -net user -redir tcp:19043::22 -monitor stdio
SOLVED: not a QEMU problem at all..installers eject CD media when done and QEMU emulates this action correctly.

I've been trying out qemu to play around with some VMs. It's working well but I keep wanting to be able to view the text (linux boot process) that quickly scrolls by in the qemu window on startup of my linux virtual machine. Is there any way to retrieve this via qemu?

I'm running Fedora x86_64. I need to setup a virtual machine to do some work on ARM platform. Thus, I've installed QEMU.
Code:
qemu --version
QEMU emulator version 0.13.0 (qemu-kvm-0.13.0), Copyright (c) 2003-2008 Fabrice Bellard
Then, I have dowloaded an ISO image of Debian 6.0 armel.Following instructions on official wiki, I have first created an empty disk image,
Code:
qemu-img create -f qcow debian-armel.img 650M
then I have attempted to boot from ISO image;
Code:
qemu -m 512 -hda debian-armel.img -cdrom debian-6.0.1a-armel-CD-1.iso -boot d
Boot process hangs with the message:
Code:
Booting from cdrom...
639 medium detected
Boot failed: Could not read from CDROM (code 0004)
No bootable device
link refers to Fedora 12, but it seems still unresolved...

When I start the laptop, booting squeeze, after the screen printed"waiting for /dev to be fully populated... conflict with acpi region smbi..." (and maybe some other msg followed) the laptop will suddenly power off and automatic restart, after several times restart, I may have good luck to log into the squeeze KDE interface. The problem also occur when I choose booting in recovery mode How can I fix this annoying problem, or where can I check the fail booting log before the restart log overwrite it?

As I walked in my office this morning, before getting withing 5 feet of my computer, the computer started an unscheduled auto reboot but failed. After hard reset, unplugging, etc., it will still not boot off of primary system. Used Live disk of previous Ubuntu to gain access to system. Found bug#407862 regarding 'rsyslogd was HUPed' but don't know what that has to do with this specific problem. [URL]. The initial error message on screen was something like "no system disk. Insert system disk and press enter", as if I had a non-bootable CDROM inserted, but there was nothing like that.
/var/log/syslog says this:
Nov 30 07:59:05 my-computer-name rsyslogd: [origin software="rsyslogd" swVersion="4.2.0" x-pid="908" x-info= URL] rsyslogd was HUPed, type 'lightweight'.
Nov 30 07:59:05 my-computer-name anacron[5755]: Job `cron.daily' terminated
Nov 30 07:59:05 my-computer-name anacron[5755]: Normal exit (1 job run)

Hundreds of previous syslog entries contain the following line:
Nov 30 08:00:01 my-computer-name CRON[6028]: (www-data) CMD (test -x /usr/bin/php && /usr/bin/php -q /usr/share/horde3/scripts/alarms.php > /dev/null 2>&1)

There seems to be a problem with Raid on Debian. I got a new Fujitsu Primergy TS 100 S1 server, with hardware Raid (and 2 disks) installed everything nicely over the net including GRUB - but when it comes to reboot the system does not boot.
Is there anybody here who knows about the problem?

After patiently waiting for 30+ hours during install attempts with the "Virtual Machine Manager", I realized that it wasn't going to happen. So then I read about a possibly working version, qemu-kvm How to use this to get a VM install up and going ? For instance, this command appears to begin an install, but where does it actually create a vm image from that?
qemu-kvm -m 512 -cdrom /iso/Fedora-14-i386-DVD.iso

ive been struggling with this for the past 4-5 days, and finally give up trying to solve it by myself. ive been following the guide here: [URL].. everything works up until i get to the iptables command, when i put it in, i get the following message:
Code: iptables v1.4.10: can't initialize iptables table `nat': Table does not exist (do you need to insmod?) Perhaps iptables or your kernel needs to be upgraded. this led me to believe that i did not configure my kernel correctly, so i rebuilt my kernel, building in all the modules that were listed. unfortunately, the only ones that were actually present in the make xconfig were

Qemu works normally for me, but the available resolutions do not include a widescreen option. Is there a work around or a command line parameter I can add to enable widescreen resolutions?

today I setup a USB drive to use Qemu to boot Backtrack. It was so easy my grandma could do this! My thanks goes out to anyone who worked on the Qemu project!Now, I am wondering, how hard it is to get a distro to run persistently, using Qemu. I would like to have my .bashrc, apps I install, small scripts I write, etc. saved instead of the default bootup each time.
It doesn't matter which distro it is as long as it is Debian based. I did find this thread which I will try later but it sounds almost like I need to boot from USB first... not quite sure. I was hoping I could get further insight from someone before I waist too much time working toward something that will not happen.

Google says this has something to do with Intel hardware and the way it handles real mode. run it with -no-kvm, but that's not much of a fix really.. so in the mean time I reverted to using qemu-kvm-devel-88 which works well, but is pretty old.

I've just installed lenny from dvd, and am just settling in. I'm curious about virtual machines. so I've installed xen. With xen comes qemu by default. Now the setup I've recently become familiar with is Suse-11 which is quite slick.In Suse, Yast provides a distribution prepared virtual management section for xen, including an installer. Debian's setup is similar but not a clone. I want to try out the installer. Aside from the differences, debian has a screaming deficit. On booting dom0 in Lenny, if fails to get into gnome, badly. I can tell what's probably wrong, but I need to fix it. Now I'm also a gentoo fan and very practised at posting queries, so here goes.
Debian's config for X is somewhat unhelpful. The xorg.conf just states Configured device and configured monitor for its components. If it expanded on just what the settings were it would help. What I have is a frambuffer driver not loadinf or being implemented.

I'm running a Windows 7 guest using Virtual Machine Manager to launch my "console" to the VM. I believe it uses VNC to connect to the console. I'd like to have clipboard synchronization so I can copy from the host and paste to the guest.

I just install QEMU and virtual machine manager to use virtualization, but virt-manager cannot run properly. I can create a VM, then mount CDROM ISO, startup. With Windows installation, it runs well until format partition step, after that it is disconected and exit with error related to VNC. I dont know why have this problem cause the packages that I installed is from Fedora repo and I think they have been tested.
Here are some infos:
Fedora 14 - kernel 2.6.35.6-45.fc14.i686.PAE
qemu-2:0.13.0-0.7.rc1.fc14.i686
libvirt-0.8.3-2.fc14.i686
virt-manager-0.8.5-1.fc14.noarch

Anyone familiar with QEMU? I'm attempting to load F15 for testing purposes along with REL 6. This is what happens, all goes well until it is actually starts downloading files to the virtual disk which appears to work until it gets to about 1/2 way completed, then it hard crashes(actually shuts the machine down). Also I had to turn of ACPI because when it is enabled it just hangs the VM altogether. I'm wondering if I should also turn off APIC?
Is there some way of loading a VM in verbose mode or debug mode to see what is happening and maybe causing this hard crash. The log files for QEMU shows nothing other then the normal loading of the virtual machine, its given name, source ISO and things of that nature.
