Also you can create VLAN subinterfaces 
on the interfaces.

This allows you to have isolated interfaces
(aliases not).

Re: Release 0.8.8 of GPL PV drivers for Windows

Well, I made the mistake of trying to run install.bat while still having 
booted w/ /gplpv. As soon as my PV nic (from 0.8.4) disappeared in Task 
Manager, I got the BSOD:

*** STOP: 0x0000007E (0xC0000005,0xF765639D,0xF8AF930C,0xF8AF9008)

***   xenenum.sys - Address F765639D base at F6540000, DateStamp 47f0c67f

Resuming the install after booting w/o /gplpv, I got the BSOD:

*** STOP: 0x0000007E (0xC0000005,0xF722F3DC,0xF8AF534b,0xF8AF5044)

***   xenpci.sys - Address F722F3DC base at F722B000, DateStamp 47f0c67f

At this point, rebooting w/o /gplpv consistently produced a hang (after the 
Windows logo). Mounting the vbd image offline, I see that the only xen*.sys 
that got updated was xenenum, so I copied the 0.8.4 xenenum on top of it, and 
rebooted w/o /gplpv. Looking in Device Manager, the only PV drivers Windows 
*thinks* are 0.8.8 are xenenum & xenpci (even tho' it never copied over 
the .sys file), and the Xen PV nic is missing again. Proceeding with 
install.bat, and I get the BSOD:

*** STOP: 0x0000007E (0xC0000005,0xF6EE52D9,0xF8AF9064,0xF8AF8D60)

***   xenvbd.sys - Address F6EE52D9 base at F6EDB000, DateStamp 47f0c67d

Can you send me the kernel config file and

Please, show the output of

# brctl show

run in dom0

and provide more info about procedure you use
to test network connectivity.

Do you want to check in the dom0 that some domU has started?
What "special network configuration" do you mean?

If you use HVM domain, 
press ctrl-alt-2 to change to QEMU monitor
and use

change 

command there.

(to activate QEMU monitor you should specify monitor=1 in the domain
config file, but it is not secure!)

Also you can use

xm block-detach
xm block-attach

to change block devices on the fly.

Please, tell what shows

when you run it after eth0 has disappeared?

xenbr1          8000.feffffffffff       no              vif3.0

As far as testing I have no connectivity on the guest OS (Suse 10.1).
Firewall is turned off. iptables -L gives:
# iptables -L
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)

You have eth0 of domain 3 connected to xenbr1 
but that's is all.

No peth1 or someting like that in dom0.

So it's normal that you can't ping any host
