Hi I have a Fedora Core 6 Xen box running two Linux hosts and one Windows Server 2003 host. I am having trouble with the Windows VM network. It was working fine but for some reason it has decided to stop. I can not ping the Windows VM for Domain-0 and I can not ping out from the Windows VM. The Windows VM has and detects the network interfaces no problem. The Windows VM network did work fine but stop for some strange reason. Both Linux hosts work fine. Each VM has two vif. Both don''t work in the problem VM. It is the last VM to be started on boot. The other two VMs have two vif each as well. vif0 is bound to eth0 and vif1 is bound to eth1. I notice this machine has only 8 loop devs could this be the problem? Any help greatly appreciated as I am stumped. xen-3.0.3-8.fc6 xen-libs-3.0.3-8.fc6 kernel-xen-2.6.20-1.2933.fc6 I get this in dmesg which I guess is my problem: device vif5.0 entered promiscuous mode ADDRCONF(NETDEV_UP): vif5.0: link is not ready device vif5.1 entered promiscuous mode ADDRCONF(NETDEV_UP): vif5.1: link is not ready Regards Daniel dir /dev/loop* brw-r----- 1 root disk 7, 0 Mar 26 20:10 /dev/loop0 brw-r----- 1 root disk 7, 1 Mar 26 20:10 /dev/loop1 brw-r----- 1 root disk 7, 2 Mar 26 20:10 /dev/loop2 brw-r----- 1 root disk 7, 3 Mar 26 20:10 /dev/loop3 brw-r----- 1 root disk 7, 4 Mar 26 20:10 /dev/loop4 brw-r----- 1 root disk 7, 5 Mar 26 20:10 /dev/loop5 brw-r----- 1 root disk 7, 6 Mar 26 20:10 /dev/loop6 brw-r----- 1 root disk 7, 7 Mar 26 20:10 /dev/loop7 The xen log: [2007-03-31 10:03:44 xend.XendDomainInfo 3301] DEBUG (XendDomainInfo:190) XendDomainInfo.create([''vm'', [''name'', ''w2k3R2-test-002''], [''memory'', 768], [''shadow_memory'', 8], [''on_reboot'', ''restart''], [''on_crash'', ''restart''], [''vcpus'', 1], [''image'', [''hvm'', [''kernel'', ''/usr/lib/xen/boot/hvmloader''], [''device_model'', ''/usr/lib64/xen/bin/qemu-dm''], [''vcpus'', 1], [''boot'', ''c''], [''vnc'', 1], [''vncunused'', 1], [''xauthority'', ''/root/.Xauthority''], [''vncpasswd'', None]]], [''device'', [''vbd'', [''uname'', ''file:/home/vm/w2k3/w2k3R2-test-002.img''], [''dev'', ''ioemu:hda''], [''mode'', ''w'']]], [''device'', [''vif'', [''bridge'', ''xenbr0''], [''type'', ''ioemu'']]], [''device'', [''vif'', [''bridge'', ''xenbr1''], [''type'', ''ioemu'']]]]) [2007-03-31 10:03:44 xend.XendDomainInfo 3301] DEBUG (XendDomainInfo:296) parseConfig: config is [''vm'', [''name'', ''w2k3R2-test-002''], [''memory'', 768], [''shadow_memory'', 8], [''on_reboot'', ''restart''], [''on_crash'', ''restart''], [''vcpus'', 1], [''image'', [''hvm'', [''kernel'', ''/usr/lib/xen/boot/hvmloader''], [''device_model'', ''/usr/lib64/xen/bin/qemu-dm''], [''vcpus'', 1], [''boot'', ''c''], [''vnc'', 1], [''vncunused'', 1], [''xauthority'', ''/root/.Xauthority''], [''vncpasswd'', None]]], [''device'', [''vbd'', [''uname'', ''file:/home/vm/w2k3/w2k3R2-test-002.img''], [''dev'', ''ioemu:hda''], [''mode'', ''w'']]], [''device'', [''vif'', [''bridge'', ''xenbr0''], [''type'', ''ioemu'']]], [''device'', [''vif'', [''bridge'', ''xenbr1''], [''type'', ''ioemu'']]]] [2007-03-31 10:03:44 xend.XendDomainInfo 3301] DEBUG (XendDomainInfo:397) parseConfig: result is {''shadow_memory'': 8, ''start_time'': None, ''uuid'': None, ''on_crash'': ''restart'', ''on_reboot'': ''restart'', ''localtime'': None, ''image'': [''hvm'', [''kernel'', ''/usr/lib/xen/boot/hvmloader''], [''device_model'', ''/usr/lib64/xen/bin/qemu-dm''], [''vcpus'', 1], [''boot'', ''c''], [''vnc'', 1], [''vncunused'', 1], [''xauthority'', ''/root/.Xauthority''], [''vncpasswd'', None]], ''on_poweroff'': None, ''bootloader_args'': None, ''cpus'': None, ''name'': ''w2k3R2-test-002'', ''backend'': [], ''vcpus'': 1, ''cpu_weight'': None, ''features'': None, ''vcpu_avail'': None, ''memory'': 768, ''device'': [(''vbd'', [''vbd'', [''uname'', ''file:/home/vm/w2k3/w2k3R2-test-002.img''], [''dev'', ''ioemu:hda''], [''mode'', ''w'']]), (''vif'', [''vif'', [''bridge'', ''xenbr0''], [''type'', ''ioemu'']]), (''vif'', [''vif'', [''bridge'', ''xenbr1''], [''type'', ''ioemu'']])], ''bootloader'': None, ''cpu'': None, ''maxmem'': None} [2007-03-31 10:03:44 xend.XendDomainInfo 3301] DEBUG (XendDomainInfo:1264) XendDomainInfo.construct: None [2007-03-31 10:03:44 xend.XendDomainInfo 3301] DEBUG (XendDomainInfo:1296) XendDomainInfo.initDomain: 5 1.0 [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: boot, val: c [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: fda, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: fdb, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: soundhw, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: localtime, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: serial, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: std-vga, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: isa, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: vcpus, val: 1 [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: acpi, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: usb, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: usbdevice, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (image:329) args: k, val: None [2007-03-31 10:03:44 xend 3301] DEBUG (balloon:127) Balloon: 810284 KiB free; need 808756; done.
