Trouble installing Windows HVM on 3.1
by Johnson, Tony M 11 Jul '07

11 Jul '07

All, Whether I utilize the DVD or ISO image, once the initial setup is completed, rebooted and restarted, I get the following pop-up: "The file 'asms' on Windows XP Professional Service Pack 2 CD is needed" Has anyone experienced and solved this problem using x64? Tony

CentOS 5 guest sees only one CPU
by Kyle Tucker 10 Jul '07

10 Jul '07

Hi, We have set up Xen on Fedora Core 5 Domain0 with a CentOS 5 HVM. This is a Dell Poweredge SC1430 system. We've set vcpus=2 and it will only see one CPU. I've also tried setting cpus="1,2" or "6,7" to no avail. Here's what xm reports when I've set cpus="6,7". # xm vcpu-list Name ID VCPUs CPU State Time(s) CPU Affinity Domain-0 0 0 6 -b- 3304.1 any cpu Domain-0 0 1 1 -b- 245.0 any cpu Domain-0 0 2 0 -b- 198.5 any cpu Domain-0 0 3 5 -b- 901.3 any cpu Domain-0 0 4 4 -b- 192.6 any cpu Domain-0 0 5 2 -b- 236.0 any cpu Domain-0 0 6 0 r-- 240.8 any cpu Domain-0 0 7 3 -b- 200.9 any cpu vm2 67 0 7 -b- 45.2 6-7 vm2 67 1 - --p 0.0 6-7 The following is in vm2's dmesg output, and I suspect the line about not detecting a SMP motherboard begins to point at the issue.

guest domain couldn't be started
by taoj2＠cs.rpi.edu 10 Jul '07

10 Jul '07

Hi, I install a guest Fedora inside the host Fedora. When I use the service xend status to check the status of xend. It shows xend is running. However when I use xm create xen1 to start the guest domain xen1, it failed. The corresponding file xen1 is in /etc/xen/xen1. The error msg is as follows: [root@phillis xen]# xm create xen1 Using config file "./xen1". Going to boot Fedora Core (2.6.19-1.2911.6.5.fc6xen) kernel: /vmlinuz-2.6.19-1.2911.6.5.fc6xen initrd: /initrd-2.6.19-1.2911.6.5.fc6xen.img Error: Device 0 (vif) could not be connected. Could not find bridge device xenbr1 I found the following line in file /etc/xen/xen1, vif = [ 'mac=00:16:3e:5c:5c:31, bridge=xenbr1', ] Why device 0 couldn't be connected? I don't know the usage of the bridge device, xenbr1. Anybody has similar problem ? Or know how to slove this problem? THanks. Best Angel

ups connected to serial port, but can't communicate via ttyS0
by Ranbir 09 Jul '07

09 Jul '07

Hi, I tried to use ttyS0 in dom0 for a serial interface UPS, but apcupsd complains that it can't talk to ttyS0. I look through /var/log/messages, and sure enough, xen is using it: Jul 3 09:45:22 xenmaster kernel: Xen virtual console successfully installed as ttyS0 Can that be turned off, so that ttyS0 isn't used by Xen? I tried to do this several months ago, but back then I was told Fedora was working towards fixing the serial port access problems.

Not seeing all RAM
by Ranbir 09 Jul '07

09 Jul '07

Hello, I'm running a FC6 dom0, with kernel version, kernel-xen-2.6.19-1.2895.fc6 on a Dell PowerEdge 1600SC. I just upgraded it from 1 GB (2 x 512 MB modules) to 3 GB (2 x 1 GB + 2 x 512 MB). The BIOS sees all of the ram, but kernel does not. All I see when I run free is this: total used free shared buffers cached Mem: 2454528 207876 2246652 0 11032 47380 -/+ buffers/cache: 149464 2305064 Swap: 524280 0 524280 It looks like 512 MB is missing. Here's a bit more detail from dmesg: Memory: 2874124k/2987900k available (2166k kernel code, 104532k reserved, 1100k data, 184k init, 2242436k highmem) So, what happened to the rest of the RAM? I should add that the server is updated with the latest firmware and BIOS. BTW, I appear to be having problems with one of my domUs now too (after the ram upgrade). A PCI device I was handing to the domU is now causing the domU kernel to panic, crashing the domU. I'll try to get a copy of the error message. Any help appreciated.

Xen kernel doesn't boot for me
by Doug Eubanks 09 Jul '07

09 Jul '07

I've tried the xen kernel on Fedora 6, CentOS 5 and now I'm running Fedora 7. Each time, it seems to hang during or perhaps right after the SCSI hardware is initialized. It doesn't panic, although it sometimes prints messages about USB devices not accepting new addresses (but not always). I am attaching my SCSI and CPU info, if anyone has a suggestion to fix or troubleshoot this I would appreciate any information.

How to shutdown a hvm guest gracefully?
by Felix Schwarz 06 Jul '07

06 Jul '07

Hi, sometimes I forget to shutdown my hvm guests before restarting the host machine. I want to prevent this/automatically shutdown the guests gracefully (as if I typed 'poweroff' on the guest's console) http://fedoraproject.org/wiki/FedoraXenQuickstartFC6: > To gracefully power off a guest use: > # virsh shutdown <virtual machine (name | id | uuid)> On my FC6 (x86_64) machine this is only works for pv guests. Unfortunately, I use several hvm guests (e.g. 32 bit guests for FC{5,6,7} which can not be run under the current 64 bit xen in FC7 - AFAIK). However, all these guests are linux machines which can be powered off by sending "Ctrl+Alt+Del". Is there any possibility to gracefully shut down linux hvm guests? fs
