[ovs-dev] [PATCH] OVS: add some tips for kvm guest env

[Zhi Yong Wu]

I tried to install OVS on my workstation, before starting kvm guest,
its route table is below:
default via 9.115.122.1 dev em1
9.115.122.0/24 dev em1  scope link

then i started kvm guest:
qemu-system-x86_64 -drive
file=/home/zwu/misc/image/debian_squeeze_i386_desktop.qcow2,if=virtio
-kernel arch/x86/boot/bzImage -append root=/dev/vda1 rw console=ttyS0
-drive file=/btrfs.img,if=virtio -drive file=/btrfs1.img,if=virtio
-drive file=/btrfs2.img,if=virtio -drive file=/btrfs3.img,if=virtio
-nographic -S -s -m 10240M

After kvm guest is started up, i tried to ping the host in kvm guest,
but it failed.
After i changed its route on the host as below:
default via 9.115.122.1 dev br0
9.115.122.0/24 dev br0  scope link
I again tried the host in kvm guest, and it can work.

Is it clear to you?
