Hello, Gerhard
I've tested telnet connections on Knoppix running on QEMU-KVM with patch V5.
Everything works fine on my setup.
What is your network setup? How do you connect tap1 interface to the
outer world?
Hello Dmitry ,
Did you also test with tap?
As patch V2 (i think it was that version) worked well but was not stable
I'm guessing that there might be some other problems:
1.) tap interface?
2.) TCP offload checksumming (as far as I saw I think there were some
changes).
Same command line with pcnet is also ok (changed only interface card).
My network setup for testing several adapters is stable since about one
year.

I use a bridge on eth0 and connect the tap interfaces:
brctl show
bridge name bridge id STP enabled interfaces
br0 8000.001fc689da45 no eth0
tap0
tap1
Also, since you have ping failure to init MSI-X is not related to the
problem - device just falls back to MSI interrupts,
but anyway, why does it fail? Could it be some QEMU/KVM versions
incompartibility?
Don't know why it fails. I'm using latest git QEMU/KVM version.
Will try it on qemu only today in the evening.
Thnx.
Ciao,
Gerhard
Best regards,

Hello Dmitry,
Tried also v5 patch without success:

ping ok, but outside tcp communication fails:
# timeout Knoppix => outside
telnet 192.168.0.2 22
# timeout outside => Knoppix failes
telnet 192.168.0.30 22
RTL8139 with same command line is ok.
Maybe that helps directly at startup:
kvm_msix_vector_add: kvm_add_msix failed: No space left on device

I'm using git qemu-kvm and not git qemu.

Hello, Gerhard
I've rechecked SSH connection both incoming and outgoing with patch v5.
Everything works fine.
If you still see problems, please, provide your exact configuration.
Thanking you for your support,

Hello,
I'm still having problems with v4 patch: ping works well, even with large
packet sizes but ssh doesn't work at all.
Tested with Knoppix 6.7 and Fedora 16.
Thnx.
