Subject: Question about starting 2 VMs using Qemu
Date: Fri, 6 Aug 2010 07:09:01 -0700	[thread overview]
Message-ID: <C881658D.261D8%anjali@juniper.net> (raw)
In-Reply-To: <AANLkTink7xb0O7W2On6g613xEJ11K0dGuq=L-wKJ=W+h@mail.gmail.com>

Hi,

I can start my freebsd based image in Qemu, and I use tap interface for
connectivity to the host or external world, but when I try to fire up 2
instances, using tap, it fails. For the second invocation, it gives me the
error:

[root@ipg-virt01 tmp]# ./qemu-system-x86_64 -m 512 anjali.img -net
nic,model=yukon,macaddr=52:54:00:00:aa:02 -net tap,ifname=tap0,script=no
warning: could not configure /dev/net/tun: no virtual network emulation
Could not initialize device 'tap'

Am I doing something wrong? The first instance is running fine.

Anjali
