No does not help. The bridge is created in /etc/network/interfaces (debian):
iface tap0 inet manual
auto br0
iface br0 inet static
bridge_ports tap0
bridge_stp off
bridge_maxwait 0
bridge_fd 0
address 192.168.0.1
netmask 255.255.255.0
I'm using kvm version:
QEMU emulator version 0.13.0 (qemu-kvm-0.13.0 Debian 0.13.0+dfsg-2), Copyright
(c) 2003-2008 Fabrice Bellard
with kvm_intel
on kernel:
Linux example.com 2.6.32-5-amd64 #1 SMP Wed Jan 12 03:40:32 UTC 2011 x86_64
GNU/Linux
I also tried -no-kvm, -no-kvm-irqchip and -no-kvm-pit. Didn't help.
Even connecting to the local machine has this 30 seconds delay (only if I use
192..., localhost is ok)
Check reverse dns resolution and firewall rules. Don't seem to be a kvm
problem.
