Single User Mode

by Boin, Paul (Cont, ARL/CISD)

I'm testing some kickstarts on xen. Everything's OK, but I'm stuck on one part. I've researched my question well, and I'm just not getting one piece. The pw set during install is intentionally bogus. I now want to go to my grub menu, go single-user and set it via 'passwd'. ( Which we typically do on non-virtual installations. ) On RHEL, where I have much more experience, I can just "xm create -c mydomain" to get an immediate attach and see the grub menu. It looks like this newer xen/libvirt on FC8 is setup to use virsh, and it has the XML configs over in /var/lib/xend/domains/, etc. So, how do I get to the grub menu using virsh, since xm seems to want to work with plaintext configs in /etc/xen, which I do not have? Or, how would you suggest I change the bogus root pw, that no one knows? Thanks and have a fine day. # rpm -q xen xen-3.1.0-13.fc8 # rpm -q libvirt libvirt-0.3.3-2.fc8

virt-install hangs for fc6,7

by john maclean

Hey guys, First post and apologies if this has been up OT before. virt-install fails to create a domU for FC6/7. Distro of node is BLAG, an FC derivative. Just jump to the end to the end of the boot up message to see where the domU hangs. /var/log/xen/xend.log indicate no warnings or explanations why this domain has failed to be "born".

Booting from floppy image

by Costa Kavanides

I read other entries about this subject but none explain why it is not possible to boot from a floppy image with XEN even though it is possible to do so with QEMU. Under dom0(2.6.21-6.fc7xen) I issue the command: qemu -boot a -fda <my-floppy-image> -hda <my-C-disk-image> and I get to boot from the floppy image, whereas when I use xen whose config file contains 'file:<my-floppy-image>,ioemu:fda:fda,r' or 'file:<my-floppy-image>,fda,r' in the <disk> clause, I get the following message in the booting window: Booting from Floppy... Boot from Floppy failed: could not read the boot disk FATAL: No bootable device. The QEMU monitor shows that, while disk-C image was taken into consideration as such, the equivalent <file> command for the floppy disk was completely ignored. Furthermore, it expects the floppy media to be present in the drive, as the following lines from the monitor's <info block> command show: hda: type=hd removable=0 file=<my-disk-C-image> ro=0 drv=raw hdb: type=cdrom removable=1 locked=0 [not inserted] fda: type=floppy removable=1 locked=0 [not inserted] Can somebody explain whether that behaviour was the result of a design choice or error? Let me emphasize the importance to have this feature. Thanks, Costa ____________________________________________________________________________________ Looking for last minute shopping deals?

AMD 64 X2 5200 - XEN only detects one core

by Darryl Bowler

I have an ACER AM3100-UD5200A which uses an AMD 64 X2 5200. Xen only detects one of two cores First I installed Fedora 8 + Xen that ships with the distro and found that only one core was detected when DOM0 booted. Out of frustration I decided to install CentOS 5.1 as a quick resolution to the problem, but found the same problem. checking /proc/cpuinfo there is only one core [root@dom0 lib]# more /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 67 model name : AMD Athlon(tm) 64 X2 Dual Core Processor 5200+ stepping : 2 cpu MHz : 2593.594 cache size : 1024 KB physical id : 0 siblings : 1 core id : 0 cpu cores : 1 fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu tsc msr pae mce cx8 apic mtrr mca cmov pat pse36 clflush mmx fxsr sse sse2 ht sysca ll nx mmxext fxsr_opt lm 3dnowext 3dnow pni cx16 lahf_lm cmp_legacy svm cr8_legacy bogomips : 6485.48 TLB size : 1024 4K pages clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: ts fid vid ttp tm stc Heres dmesg from CentOS Bootdata ok (command line is ro root=/dev/VolGroup00/LogVol00 rhgb quiet) Linux version 2.6.18-53.el5xen (mockbuild(a)builder6.centos.org) (gcc version 4.1.2 20070626 (Red Hat 4.1.2 -14)) #1 SMP Mon Nov 12 02:46:57 EST 2007 BIOS-provided physical RAM map: Xen: 0000000000000000 - 00000000a5250000 (usable) On node 0 totalpages: 676432 DMA zone: 676432 pages, LIFO batch:31 DMI 2.5 present.

inittab corrupted/serial console broken on Xen-ified kernel?

by Evan Lavelle

[this is a message that I sent to xen-users yesterday, but I guess this list may be better - this looks like a problem either in Xen, or in the packaging of 2.6.21-2952.fc8xen]. I've just installed Fedora 8 / xen-2.6.21 on a headless server, but I can't get a serial console login on the Xen version of the kernel. 1 - If I boot into 2.6.23.8-63.fc8, the serial console login works as expected 2 - If I boot into 2.6.21-2952.fc8xen instead, I get all the expected serial output up to the end of the boot process, but no login. When I boot into the xen kernel, inittab is modified, and the modification removes the agetty on ttyS0. If I compare the old inittab with the new inittab, I get: 46,47c46 < # co:2345:respawn:/sbin/agetty xvc0 96 9600 vt100-nav < co:12345:respawn:/sbin/agetty ttyS0 115200 vt100 --- > co:2345:respawn:/sbin/agetty xvc0 96 9600 vt100-nav In other words, a commented entry was uncommented, and the following line was deleted, which explains why I can't log in. This is so bizarre that it almost looks like it was done on purpose (was it ? :)) Anyone seen this? Any ideas? Thanks - Evan

Problem installing a para 32 bit FC5 guest on a 32 bit FC7 domU

RE: [Fedora-xen] (no subject) - (Win HVM not booting) - FIXED!

by Gary Catalano

Thanks to everyone who sent me responses on my original issue. I got it resolved and it's humming along! =) I've been doing some benchmarking on my Windows-on-Xen instance and the numbers are pretty low for certain kinds of tests. Is there a general assumption about the performance that one can expect from a Xen-instance (i.e. 70% of the speed of a real system, etc.)? I've got my virtual machine running with 1 virtual cpu and 2gb of RAM, running windows xp. Many thanks! Gary Catalano

align fix for vmm-create.glade

by Dan Horák

Hello, in the virt-manager's new VM wizard there is a small alignment inconsistency on the "Locating installation media" page for paravirtualized machine. The second and third label are right aligned, while the first (Install Media URL) is not. The included patch fixes this issue. With regards, Dan Horak
