OK. Now host's app.s have access to Internet through the bridge. At the beginning I mixed up things w/ bridge because I tried to set LAN also at the same time - I just did not follow the howto. :) Pardon. But I can not start kvm. That's what I do: $ /usr/bin/kvm -localtime -m 256 -no-reboot -boot c -hda da -net nic,macaddr=$(printf 'DE:AD:BE:EF:%02X:%02X\n' $((RANDOM%256)) $((RANDOM%256))) -net tap kvm: -net tap: could not configure /dev/net/tun (tap%d): Operation not permitted kvm: -net tap: Device 'tap' could not be initialized I run it under normal user - as You have guessed already - yet in sudoers I have for the user (as I understand all the commands involved in tap bringing up by KVM): vmuser ALL = /sbin/ifconfig *, /sbin/ifup br0, /sbin/ifdown br0, /sbin/ip *, /sbin/brctl *, /usr/sbin/tunctl *, /sbin/route add -host * How I can solve this? By the way, to overrun the permission problem I have tried running it under sudo (root) user when I got the following error: No protocol specified Could not initialize SDL(No available video device) - exiting So it needs a screen for KVM window running. Do You know how I can launch it in such case? - Except to allow root user. :) >> >> 2.

Now I have performed that under normal user. And I can reach the guest from host. My problem here is that I can not give Internet access to the guest. I tried w/ NAT on host and routing tables on both host and guest, but w/o success. For those movements please read my previous letter. >See my other mail.

My host is connected to router. Do You mean that I need NAT at the router or host? - I thought host only.
