[Xen-users] Weird bridge problem Xen 4 + Debian Squeeze + HVM
Hi all, I''ve a Debian Squeeze 64bits box with Xen 4 from deb repositories and PV/HVM support. root@debian:~# xm info |grep xen_caps xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64 I''m trying to do a Windoze HVM but I''ve no network at all. This is the cfg file: ##################### import os, re arch = os.uname()[4] kernel = "/usr/lib/xen-4.0/boot/hvmloader" builder=''hvm'' vcpus = ''1'' memory = 512 shadow_memory = 8 name = "xp1.canonigos.es" vif = [ ''type=ioemu, bridge=eth0'' ] disk = [ ''phy:/dev/mapper/vserver-xp1,ioemu:hda,w'', ''file:/root/xp.iso,ioemu:hdb:cdrom,r'' ] device_model = ''/usr/lib/xen-4.0/bin/qemu-dm'' # boot on floppy (a), hard disk (c) or CD-ROM (d) # default: hard disk, cd-rom, floppy boot="dc" sdl=0 vnc=1 vnclisten="0.0.0.0" vncconsole=1 vncpasswd=''canonigos'' stdvga=0 serial=''pty'' usbdevice=''tablet'' on_poweroff = ''destroy'' on_reboot = ''restart'' on_crash = ''restart'' ######################## With this config I''ve no network inside the domU-HVM but PV domU''s with Debian works great. If I change vif= statement to type=paravirtualized the domU-HVM doesn''t recognize the PCI Network device. There''s some bug rolling'' here? Thanks!

Re: [Xen-users] Weird bridge problem Xen 4 + Debian Squeeze + HVM
you specify eth0 as the bridge interface? does eth0 is really a bridge? what''s the output of brctl show?

Re: [Xen-users] Weird bridge problem Xen 4 + Debian Squeeze + HVM
Without the VM-HVM running...
root@debian:~# brctl show
bridge name bridge id STP enabled interfaces
eth0 8000.002215e17c2f no peth0
VM-HVM Running:
root@debian:~# brctl show
bridge name bridge id STP enabled interfaces
eth0 8000.002215e17c2f no peth0
vif1.0
If I use type=paravirtualized in the vif statement and add to the iso the
GPLPV drivers (with nLite) the network works in the HVM domU (WinXP) but the
default type=ioemu doesn''t works.
With Xen 3.4.2/Lenny dom0 it works flawlessly !! But Squeeze/Xen4
doesn''t.
Any ideas?

As said in the Xen 4.1 release notes, thoose scripts are very fragiles and I personnally find them evry complicated for what they really do: configure the dom0 network. In the past I remember having some issue related to arp being disabled on some underlying device or being nabled whereas it should not... As you can see I don''t clearly remember. :) If you want to stick with the network-bridge scripts of xen ... may be you can take a look at the ARP options of the devices. I would recommend you let the OS take care of Dom0 network config (furthermore Xen 4.1 doesn''t provides thoose scripts anymore i think). I personnally use network-dummy as the network-script in xend-config.sxp and configure Debian to setup a bridge at startup like this: auto xenbr0 iface xenbr0 inet static address 192.168.x.y netmask 255.255.a.b broadcast 192.168.x.255 gateway 192.168.x.z bridge_ports eth0 bridge_fd 3 bridge_maxwait 5 This config allow HVM (here a vista host) to access network with the following in its configfile: vif = [ ''bridge=xenbr0'' ] Hope it helps.> > VM-HVM Running: > > > root@debian:~# brctl show > bridge name bridge id STP enabled interfaces > eth0 8000.002215e17c2f no peth0 > vif1.0 > > > If I use type=paravirtualized in the vif statement and add to the iso > the GPLPV drivers (with nLite) the network works in the HVM domU > (WinXP) but the default type=ioemu doesn''t works. > > > With Xen 3.4.2/Lenny dom0 it works flawlessly !!

Re: [Xen-users] Weird bridge problem Xen 4 + Debian Squeeze + HVM
Hi, thanks for the info! I''d solved the problem ''partially'' running the VIF of the HVM domU with type=paravirtualized and modifying the Install ISO image with the gplpv drivers. I have a clone system for testing a development and will probe adding my own bridge. I have another issue now. The first time I''d install this system was in 192.168.13.0/24 network. The final network for this Xen host is not the same (192.168.5.0/26). I''d modified the network (/etc/network/interfaces) into dom0 to 5.0/26 final destiny and the domU too. But the PV domU''s that had installed into 13.0/24 doesnt'' have internet access now. I can ping them put they don''t resolv or ping gateway. There''s a place where Xen store this data and could be modified to reflect this network changes? (Other than network/interfaces or network/resolv.conf) Any help is appreciated.. Thanks!
