7081,Routed networking to hostonly if extremely slow after upgrade to 3.2.6 => Fixed in 3.2.8,Martin,,"In our setup VMs use host-only networking. VPN and external traffic is forwarded using iptables to the VMs. After upgrade from 3.2.4 to 3.2.6 this traffic became real slow:

From an host connected through the vpn with 3.2.4:

{{{
scp root@10.101.2.101:/var/lib/aptitude/pkgstates .
pkgstates  100% 2069KB   2.0MB/s   00:01
}}}

On 3.2.6:
{{{
scp root@10.101.2.101:/var/lib/aptitude/pkgstates .
pkgstates  100% 2069KB  15.9KB/s   02:10
}}}

On the host itself communication to the VMs is fast. Slow networking only occurs when routed (FORWARDed) through iptables.

Host is 64bit Lucid (running on i7 920 with 24GB ram), guests are 32 bit karmics.

Downgrading to 3.2.4 solved the speed problem, but the extensive logging came back (Ticket #6872). May be the fix for 6872 is related to this issue?",defect,closed,network/hostif,VirtualBox 3.2.6,fixed,,,Linux,Linux
