Hi all.
I've been playing around with KVM for a bit now and have several virtual
machines up and running. Having passed what I considered "first look"
stage, I'm ready to start using libvirt as a manager. For reference,
pre-libvirt, I have started this VM with:
/kvm -net nic,model=virtio -net tap,ifname=tap5,script=no -drive
file=test1.img,if=virtio,boot=on -curses -no-reboot -m 1g -smp 2/
I have a test environment I like to play with, and created the initial
domain XML using virt-install:
/virt-install --name "Test" --ram 1024 --vcpus=2 --cpu host
--description "Test VM" --import --file test1.img --os-type=linux
--os-variant=virtio26 --network bridge=br0,model=virtio --graphics=none
--autostart --prompt/
When I look in /var/log/libvirt/qemu/Test.log I see the VM is started
with the command (edited down to the relevant parts):
//usr/bin/qemu-kvm -S -m 1024 -smp 2 -name Test,process=qemu:Test
-nographics -boot c -drive file=/kvms/test1.img,if=none,boot=on
/This has two problems:
1) The "-S" is keeping the system from booting
2) the "if=none" needs to be "if=virtio"
I've confirmed both by changing -nographics to -curses and watching what
happens. For #1, its a big fat nothing (no surprise since -S turns off
the CPUs), for #2 grub loads and the kernel boots, but my /dev/vda3
isn't found so "init" can't start.
I'm anticipating a 3rd problem: I don't see where to specify that I
want the VM to use "tap5" of my bridged network.
Can some kind soul please let me know what I need to change in the
domain XML file to fix these issues?
Thanks,
Kevin

would prefer to answer there.
