hi, I try to get the Centos.5-1.64 image from Jailtime.org running in a Centos5 / Fedora8 Dom0, but it complains that there's no sda1 in the DomU. I tried both file- and lvm-backed VBDs, but with no luck: [...] Initializing IPsec netlink socket NET: Registered protocol family 1 NET: Registered protocol family 17 XENBUS: Device with no driver: device/vbd/2049 XENBUS: Device with no driver: device/vbd/2050 XENBUS: Device with no driver: device/vif/0 md: Autodetecting RAID arrays. md: autorun ... md: ... autorun DONE.

iwl3945 driver
by Jason Solan 18 Apr '08

18 Apr '08

Hello, I am wondering if anyone has the iwl3945 driver working on xen? I'm using Fedora 8 and under the standard kernel the driver works great. When i switch the xen kernel, fedora can no longer find the device. If I do a kudzu -pc NETWORK the device shows up (as eth1 instead of wlan0) but it does not have a mac address. I've tried just manually adding the entry and its mac address to /etc/sysconfig/hwconf but that didn't seem to do anything for me. Any help is appreciated. --Jason IMPORTANT: This transmission is sent on behalf of Knouse Foods for business purposes. It is for the intended recipient only.

ANNOUNCE: virt-df ('df' for guests) now supports LVM
by Richard W.M. Jones 17 Apr '08

17 Apr '08

I'm happy to say that virt-df, the command-line 'df'-like tool for looking at disk usage of guests, now supports LVM, making it usable for the majority of situations where your guests are running Linux distributions. You can now run 'virt-df' on the host and display the disk space used/available on all filesystems of all your guests. There is no need to run anything inside the guest. Here is an example with two running domains: # virt-df -c qemu:///system -h Filesystem Size Used Available Type rhel51x32kvm:hda1 96.8 MiB 14.6 MiB 82.2 MiB Linux ext2/3 rhel51x32kvm:VolGroup00/LogVol00 6.4 GiB 3.6 GiB 2.8 GiB Linux ext2/3 rhel51x32kvm:VolGroup00/LogVol01 992.0 MiB Linux swap rhel51x64kvm:hda1 96.8 MiB 22.1 MiB 74.7 MiB Linux ext2/3 rhel51x64kvm:VolGroup00/LogVol00 6.4 GiB 3.2 GiB 3.2 GiB Linux ext2/3 rhel51x64kvm:VolGroup00/LogVol01 992.0 MiB Linux swap Home page: http://et.redhat.com/~rjones/virt-df/ Source and binaries from: http://et.redhat.com/~rjones/virt-df/files/ Rich. -- Richard Jones, Emerging Technologies, Red Hat http://et.redhat.com/~rjones virt-p2v converts physical machines to virtual machines.

Weird routing problem
by Turbo Fredriksson 17 Apr '08

17 Apr '08

I have two physical hosts (Correo and Alexander), running two XEN instances on one of them (Ferrari and Amarillo on Correo) and one on the other (Graham on Alexander)... Picture at http://bayour.com/misc/VoIP.jpg. On the firewall/gateway (192.168.1.1) I route 192.168.3.0/24 to Correo (192.168.1.7) and 192.168.4.0/24 to Alexander (192.168.1.6). This so that I can access the XEN hosts from the internal network. Very basic... And all my VoIP phones is on it's (about to be on a) separate network with the firewall/gateway as default gateway. On Alexander: ============= * /etc/xen/graham.cfg kernel = '/boot/vmlinuz-2.6.18-5-xen-amd64' ramdisk = '/boot/initrd.img-2.6.18-5-xen-amd64' memory = '2500' root = '/dev/sda1 ro' disk = [ 'file:/home/xen/domains/graham/disk.img,sda1,w', 'file:/home/xen/domains/graham/swap.img,sda2,w' ] name = 'graham' vif = [ 'ip=192.168.4.11' ] on_poweroff = 'destroy' on_reboot = 'restart' on_crash = 'restart' * /etc/xen/xend-config.sxp (xend-http-server yes) (xend-unix-server yes) (xend-tcp-xmlrpc-server no) (xend-unix-xmlrpc-server yes) (xend-relocation-server yes) (xend-unix-path /var/lib/xend/xend-socket) (xend-port 8000) (xend-relocation-port 8002) (xend-address 'alexander') (xend-relocation-address 'alexander') (console-limit 1024) (network-script network-route) (vif-script vif-route) (dom0-min-mem 196) (dom0-cpus 2) (enable-dump yes) (vnc-listen '0.0.0.0') * ifconfig (trimmed - only 'lo' if removed) eth0 Link encap:Ethernet HWaddr 00:1C:23:C4:28:92 inet addr:192.168.1.6 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::21c:23ff:fec4:2892/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 eth0:0 Link encap:Ethernet HWaddr 00:1C:23:C4:28:92 inet addr:192.168.4.1 Bcast:192.168.4.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 vif5.0 Link encap:Ethernet HWaddr FE:FF:FF:FF:FF:FF inet addr:192.168.1.6 Bcast:192.168.1.255 Mask:255.255.255.255 inet6 addr: fe80::fcff:ffff:feff:ffff/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 * route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.4.11 0.0.0.0 255.255.255.255 UH 0 0 0 vif5.0 192.168.4.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 0.0.0.0 192.168.1.1 0.0.0.0 UG 0 0 0 eth0 * iptables -L -n Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination ACCEPT 0 -- 192.168.4.11 0.0.0.0/0 PHYSDEV match --physdev-in vif5.0 ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 PHYSDEV match --physdev-in vif5.0 udp spt:68 dpt:67 Chain OUTPUT (policy ACCEPT) target prot opt source destination * iptables -L -n -t nat Chain PREROUTING (policy ACCEPT) target prot opt source destination Chain POSTROUTING (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination On Graham: ========== * ifconfig (trimmed - only 'lo' if removed) eth0 Link encap:Ethernet HWaddr 00:16:3E:00:AB:28 inet addr:192.168.4.11 Bcast:192.168.4.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 * route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.4.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 0.0.0.0 192.168.4.1 0.0.0.0 UG 0 0 0 eth0 * iptables -L -n FATAL: Could not load /lib/modules/2.6.18-5-xen-amd64/modules.dep: No such file or directory iptables v1.3.6: can't initialize iptables table `filter': iptables who?

F9 Feature List correction
by Alroger L. Gomes F. 16 Apr '08

16 Apr '08

In the Feature List Accepted Features (http://fedoraproject.org/wiki/Releases/9/FeatureList) Xen paravirt_ops should say 50% or less, instead of 100%, since Dom0 XEN is NOT working in Fedora9, since it's description includes Dom0: "Replacing the current forward-ported XenSource code on kernel-xen by a paravirt_ops based implementation, including dom0 suppor" - 2008-04-07 Acording to http://fedoraproject.org/wiki/Features/XenPvopsDom0, Dom0 is at 30% still. -- I see babies crying...

Hi, I'm trying to start Xorg on a PV Fedora8 guest running 2.6.21.7 fedora stock xen kernel, however, it seems that there's no xenfb.ko driver included in the .rpm package. The only included drivers I see in /lib/modules are: emre@xenroot:/lib/modules/2.6.21.7-3.fc8xen/kernel/drivers/xen$ ls blkback blkfront blktap netback netfront pciback however, if I look at the source rpm: emre@xenroot:/d/xen/fedora8/xen-3.1.3/linux-2.6-xen-sparse/drivers/xen$ ls balloon blktap core gntdev netback pcifront util.c blkback char evtchn Kconfig netfront privcmd xenbus blkfront console fbfront Makefile pciback tpmback xenoprof I can clearly see the fbfront directory, with "xenfb.c xenkbd.c" files inside. Is there a specific reason why these drivers are excluded from the default build? Thanks a lot for your comments. Emre
