paravirtualized windows net driver stop after some days on XP guest

paravirtualized windows net driver stop after some days on XP guest

[Yann Dupont]

Hello. I'm using kvm whit great succes for various OS. Very good job.

In June I started using paravirtualized drivers.

Since that we encountered sporadic loss of connectivity on some Xp
guests after some days of uptime.
This was with KVM 70. I upgraded to KVM 73 4 days ago, and this morning
1 off my Xp guests had no connectivity.

Putting the interface off then on via panel control  revives network
instantly.  Seems like a bug on the windows driver side .
This is occurring on 2 Xp guests, they have moderate to low network load.

They have 1 CPU , the hal is the non acpi one (because they were
installed in KVM-23 timeframe)

I also have 2003 guests, and so far I haven't encountered the problem.

Also have linux guests, with net AND disk virtio , AND high load without
problem.
Best Regards,

Can you please try an update version of the windows drivers?
I also added a dummy installer you can use too:

Well, installation is OK.
Now running this driver on some XP & 2003 machines. So far, so good.

Time will tell if stability is ok.
Thanks for your quick answer,

paravirtualized windows net driver for vista does not work on windows 2008 (64-bit)

[Martin Maurer]

Hi all,

I tried to use the vista virtio driver on win2008 (64-bit) but the install failed, I got this in the windows event log:
I am working on a Debian Etch 64 bit Kernel 2.6.24 with KVM 74 (internal testing Kernel of http://pve.proxmox.com) 

I used the following driver: http://people.qumranet.com/dor/Drivers-0-3107.iso

Re: paravirtualized windows net driver for vista does not work on windows 2008 (64-bit)

[Dor Laor]

Sorry for that, seems like there where some instructions missing.
Since we did not (yet & soon) sign the drivers you need to install a 
certificate workaround manually:

There are 2 things to do on 64-bit before installation.
1. Install certificate using installcertificate.bat
2. If "Test mode" does not appear on the screen, run "bcdedit /set 
testsigning on" and reboot

The system diagnostic, related to installation, on 2008 is in 
%windir%\inf\setupapi.dev.log
Please compress the file and send, if both 2 things done but the install 
does not work.

Regards,
Dor

YES, working! 

Testing again (I already have now a KVM 75, but I assume this does not make any difference here).

I followed your instructions, the driver installed without any warning as expected after installing the certificate.

The only issue: the connection shows only 100mbit - after changing this via the windows device manager, the 1 GBIT is up. Default should be 1 Gbit, is this possible? I assume a lot of people forget about changing this and then they got bad performance due to 100mbit.

Thanks,

The 100mb is not the bandwidth limitation. Nevertheless is should change.
The only worry is that in order to certify (Microsoft sign) the drivers 
I was told that 1Gb device needs to support 802.1q.
It might require some simple qemu virtio changes like like vlan 
filtering and tag on/off options.
