December 22, 201312 yr Author It couldn't be that easy, could it? bigmama /home/VMs/unRAID # xl create unRAID.cfg Parsing config from unRAID.cfg libxl: error: libxl_exec.c:118:libxl_report_child_exitstatus: /etc/xen/scripts/vif-bridge online [1925] exited with error status 1 libxl: error: libxl_device.c:1021:device_hotplug_child_death_cb: script: Could not find bridge device xenbr0 libxl: error: libxl_create.c:1115:domcreate_attach_vtpms: unable to add nic devices libxl: error: libxl_exec.c:118:libxl_report_child_exitstatus: /etc/xen/scripts/vif-bridge offline [1955] exited with error status 1 libxl: error: libxl_device.c:1021:device_hotplug_child_death_cb: script: Could not find bridge device xenbr0 You havn't set up a network bridge... To be fair, i havn't included that in my write up. Look here - https://wiki.archlinux.org/index.php/xen - for the section 'create a network bridge'.
December 22, 201312 yr I just followed that. I now have a xenbr0: bigmama ~ # brctl show bridge name bridge id STP enabled interfaces xenbr0 8000.00259064a7d8 no enp1s0f0 Question, once I started the bridge I was booted out of SSH and I now had to SSH back in with the IP of the bridge (192.168.1.235). Is that expected? I can no longer SSH in with the IP and enp1s0f0 (192.168.1.234) bigmama ~ # ip link 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 2: enp1s0f0: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc mq master xenbr0 state UP mode DEFAULT group default qlen 1000 link/ether 00:25:90:64:a7:d8 brd ff:ff:ff:ff:ff:ff 3: enp1s0f1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000 link/ether 00:25:90:64:a7:d9 brd ff:ff:ff:ff:ff:ff 4: xenbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP mode DEFAULT group default link/ether 00:25:90:64:a7:d8 brd ff:ff:ff:ff:ff:ff bigmama ~ # ip addr 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo valid_lft forever preferred_lft forever inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: enp1s0f0: <BROADCAST,MULTICAST,PROMISC,UP,LOWER_UP> mtu 1500 qdisc mq master xenbr0 state UP group default qlen 1000 link/ether 00:25:90:64:a7:d8 brd ff:ff:ff:ff:ff:ff inet6 fe80::225:90ff:fe64:a7d8/64 scope link valid_lft forever preferred_lft forever 3: enp1s0f1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000 link/ether 00:25:90:64:a7:d9 brd ff:ff:ff:ff:ff:ff 4: xenbr0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default link/ether 00:25:90:64:a7:d8 brd ff:ff:ff:ff:ff:ff inet 192.168.1.235/24 brd 192.168.1.255 scope global xenbr0 valid_lft forever preferred_lft forever inet6 fe80::225:90ff:fe64:a7d8/64 scope link valid_lft forever preferred_lft forever

December 22, 201312 yr What did you use the MAC addy in your unraid cfg? That's not the MAC of xenbr0 is it? vif = [ 'mac=00:16:3e:a1:b2:cc,bridge=xenbr0' ]
December 22, 201312 yr Author What did you use the MAC addy in your unraid cfg? That's not the MAC of xenbr0 is it? vif = [ 'mac=00:16:3e:a1:b2:cc,bridge=xenbr0' ] This is the mac address you're assigning the VMs virtual ethernet port and should therefore be a random collection of a1:b4:cd etc but the first few groups are unique to Xen. Google it, you'll find it.
December 22, 201312 yr NM...found this: The 00:16:3e MAC block is reserved for Xen domains, so the last three digits of the mac= must be randomly filled in (hex values 0-9 and a-f only).

December 22, 201312 yr Haven't gone the next step yet (plugging in my unraid drives and usb key). I have some other issues to work out yet with Arch/Xen. 1. xenbr0 is not establishing a link after a reboot even though I did systemsctl enable xenbridge-dhcp. I have to manually start it. 2. When I created the bridge, it whacked my enps10f0 (does not establish a link). I still no not know if this is expected but I see a failure in systemctl: 3. As you can see in the above screenshot, I also have issues with libvirt. I'll probably work with grumpy on this one unless someone else has any suggestions.
December 22, 201312 yr OK...#1 and #2 solved. grumpy had me disable enp1s0f0. xenbr0 now comes back with an IP after reboot and there is no failure in systemctl. on to #3.
December 22, 201312 yr Not using libvirt here, no ideas how to help. Why are you using the libvirt for the client / web gui?
December 22, 201312 yr Not using libvirt here, no ideas how to help. Why are you using the libvirt for the client / web gui? Trying to get virt manager going over x11 ssh.
December 22, 201312 yr Ok, got it. I'm doing everything using command line, and using the config files. Maybe I would try to get Xen working without libvirt first, and then get libvirt working on top of it once it's working.
December 22, 201312 yr Had another issue... Since disabling enp1s0f0, when I start the unraid VM, my SSH connection is dropping and I am seeing these messages in the console:
December 22, 201312 yr Author Had another issue... Since disabling enp1s0f0, when I start the unraid VM, my SSH connection is dropping and I am seeing these messages in the console: post your netctl files... ie the enp1s0f0 and bridge-dhcp files
December 22, 201312 yr post your netctl files... ie the enp1s0f0 and bridge-dhcp files We got it working. He just needed to remove his eth0 and refresh the xenbr0 with netctl.

December 22, 201312 yr grumpy was huge help as normal. I had to run some errands and take a mental break. unRAID is up and running. Still no love with XBMCbuntu in a VM. I just can't get the output to go to the Radeon card. It's like it starts to and then just gets lost in space during the transition from VNC to the TV. ESXi had no issue with this at all with nothing special other that passing through the video card. I know this has be possible in Xen! If I can just get this figured out I'll be golden.

ESXi had no issue with this at all with nothing special other that passing through the video card. I know this has be possible in Xen! It isn't you or your machine... I can't get XBMCbuntu to work in Xen on Linux either. I am testing it now in KVM. We might have to switch you to that. Let me list out all the steps to switch to KVM: 1. Boot into the Linux Kernel from grub. 2. install QEMU. Phew! You have your work cut out for you.
December 22, 201312 yr I really need a dev server. I put ESXi back up so the boys could watch a movie. At least I won't have to eject all of the unRAID drives anymore when I decide to play with Arch/Xen/KVM since we are past the install. That was the biggest PITA.
December 22, 201312 yr I received some absolutely sterling advice and help from grumpy at an unreasonable hour, which was absolutely appreciated. Whilst i had issues with amd's woeful driver support in linux regarding HD AUDIO passthrough, I am firmly of the belief that virtualisation is the way to go, luckily I have a small 250 GB slotted into a spare bay on my server that i can pull/push to give me a safe environment to muck about and explore possibilities without affecting my main system in any way. Latest venture so far, I have followed the XMBC VDPAU installation instructions in ubuntu 13.10 minimal server install to get a kernel with some patches that allows AMD graphics card to passthrough HD AUDIO (AND IT WORKS !!!!!!) , i've got a xen hypervisor up and running. It's movie time for me now (using the main system again) , but tomorrow I plan on playing with getting unraid up and running on the hypervisor instance. Once again, absolutely massive thanks to grumpy.

Are you using the Radeon Drivers (which I use) or does AMD have theirs out in beta yet?

I followed that thread to the letter and never got out to the TV. XBMC always reports that "gallium" display adapter in the Settings Info. Did you have to do anything other than what is outlined in that thread? John
