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?
View 1 RepliesI 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
I want to experiment with pacemaker, and for that I'd like to start kvm virtual machines with the snapshot option, so that as soon as I stop the vm, all changes are gone and I can start over. Since I couldn't figure out how to setup networking (vm - vm and vm - public) with a kvm commandline without disturbing the Network Manager, I used the Virtual Machine Manager (VMM) for this.
It works now, but I cant see how to use the snapshot option with the VMM. On the other hand, I cant see how I start the resulting vm from the commandline. When I look at the process list, I see the command with these network options:
Code:
-netdev tap,fd=21,id=hostnet0
-device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:45:30:b0,bus=pci.0,addr=0x3
-netdev tap,fd=22,id=hostnet1
-device virtio-net-pci,netdev=hostnet1,id=net1,mac=52:54:00:84:5b:bc,bus=pci.0,addr=0x6
How would I go about these fd=nn things on the commandline? I guess I somehow have to start the tap devices before, but how?

View 3 Replies View RelatedAfter 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)

Boot failed: Could not read from CDROM (code 0003)

SOLVED: not a QEMU problem at all..installers eject CD media when done and QEMU emulates this action correctly.
I just installed qemu and want that my VM should have net access too. So for that I installed bridge-utils and used URl....Add both the interface with the second computer, and the interface that leads to the existing network. Do it with this command: # brctl addif br0 eth0 eth1

I don't want to have it anymore, however I can't get rid of this 2GB used space with windows XP.

View 3 Replies View RelatedI'm running some vm's in FC12 with kvm-qemu and using virt machine manager. I'd like to have some ports automatically forward on startup and be able to add redirections on the fly. Redirection on the fly is talked about here, but I am getting lost on what should be basic instructions.[URL]
As far as startup, In the past I just ran qemu from the cli and manually specified redirection with redir. I can't figure out how to do it with The virt machine manager which I am using to start my VM's now. I do not want the guests to see the host. From cli startup without virt machine manager, it looked like this: qemu -m 256 -hda vm.img -redir tcp:5555::80 -redir tcp:5556::445 &
