Hi, I installed one debian HVM guest (VT virtualization). I didnt configured the network (I dont know if it is related to my problem): When I start the domU , I received this error: desktop:/etc/xen# xm create -c debian-web.cfg Using config file "./debian-web.cfg". Started domain debian-web xenconsole: Could not read tty from store: No such file or directory Here is my cfg: kernel

Hi, I''m running OpenBSD 4.5 as HVM guest. Here is part of my .cfg file: kernel = ''/usr/lib/xen-3.2-1/boot/hvmloader'' device_model = ''/usr/lib64/xen-3.2-1/bin/qemu-dm'' builder = ''hvm'' It is running fine with vnc, but when I ssh to openbsd, and I type cat, vi, etc. it freezes. Any ideas? Thanks in advance. -- Sergio Roberto Charpinel

Hi, I''ve installed XCP 0.5 and I''m following these steps: http://xenbits.xen.org/xapi/install.html to install ddk VM. But I can''t get network working. I tried to create a vif under xenbr0 then assigned mannually a IP address and to create a vif under xapi0. But in both cases I can ping only dom0 IP. What am I doing wrong? Thanks in advance. -- Sergio Roberto

Dear fellow Xen''ers! I''m having a problem with my new Xen-enabled colocation server.. I hope ( at least ;) ) one of you guys know how to fix this problem.. For a certain amount of time ( 1-2 days ) the domU runs fine.. until the console starts spitting out messages like these: [80182.004456] clocksource/0: Time went backwards: delta=-6917292717540055641 shadow=80182004054805

Package: xen-hypervisor-4.0-i386 Version: 4.0.1-2 Severity: normal Hi, Take the following config file (standard lenny kernel and initrd, with some customization for iSCSI root): name = "lenny3" kernel = "vmlinuz-2.6.26-2-686-bigmem" ramdisk = "initrd.img-2.6.26-2-686-bigmem" memory = 100 vcpus = 1 vif = [ 'mac=00:16:3e:00:00:17, bridge=br695,

Hi, I have upgraded my Dell C151 to the latest 5.6. I have always used ntp to sync this machine and then the rest of the machines in the network would sync from it. Since the update I cannot keep the right time on the machine. This is with / without ntp. I have attempted various scenario's with no luck. I am now trying the old kernel now as I type this out. If anyone else has any

Hi there, I am getting very low throughput (around 0.29Mbps) while running netperf benchmark for guest to guest communication on a single physical host. To analyse where the time is spent in hypervisor I wanna use profiling. Please help me choosing good profiler according to my requirments. Should it be better in my case, Xentrace, gprof, xenoprof  or Oprofile. Is it possible to use some vtune

(Moving from offlist discussion.) I''m interested in opinions... Assume there are four single vcpu domains A, B, C, D, running on a 2-CPU physical machine. We wish to test for time skew on domain A. Assuming B, C, and D are all running some workload that attempts to fully saturate the (single) cpu. 1) Should the affect on domain A be essentially the same regardless of what load

v3: - Various changes to dhclient/dhcpcd as discussed on the mailing list.

v2: - Make virbr0 configurable. - Fix the tests.

So yesterday I got was able to get a domU successfully using a PCI SCSI card. This morning I restarted the host server. When I try to start up the same domU I get this error: Error: pci: improper device assignment specified: pci: 0000:0e:04.0 must be co-assigned to the same guest with 0000:0e:04.0, but it is not owned by pciback. How do I make this card owned by pciback on reboot. Do I need to

I wanted to install Xen on 32bit processor with 8GB RAM. I am running Debian on it. The general Kernel can only address ~4GB of RAM. So, Is it necessary to install BigMEM kernel so that all the memory get addressed? And then install xen kernel. Or ?? Suggestions welcome.

On a selection of boxes, ntpd running in Xen Dom0 reproducibly exhibits extermely high noise/jitter. Switching back to -default, non-xen kernel ntpd runs with very low jitter/noise. Question -- how can I ''tame'' ntpd noise & jitter when running in Dom0? Is the problem a config issue, or a bug? Already reported this downstream; everybody''s "stumped".

I have a couple Debian 6 HVM VMs. From what I''ve read, Debian 6''s standard kernels have pv_ops already enabled. I''d like to convert these to pv for the following reasons (Assuming both of are valid expectations): 1) so the VMs use pv for the NICs 2) so the VMs properly respond to shutdown/reboot commands from xm I''m having trouble converting them. I believe

Hello, I guess it possible distro specific issue but is it resolvable? I have one node(testing purpose) ganeti 2.0.1 cluster installed over Debian5 Lenny. Almost everything from distro repositories. Only ganeti 2.0.1 and ganeti-debootstrap are from sources. I have it successful run with vmlinuz-2.6.26-2-xen-686 and initrd.img-2.6.26-2-xen-686 from repositories. Both Dom0 and DomU are use the

When booting 2.6.37 (from kernel.org) under Xen 4.1, there are apparently issues with timer interrupts being delivered to the dom0. Repeatedly causing an interrupt (for example, the ACPI power button) will allow the system to boot, as does adding "clocksource=jiffies" to the kernel command line. This is only present under Xen, not when booting the same kernel on real hardware. When boot

Is this a known bug? Suprisingly google didn't turn up much. I'm running DDR RAM and a AMD XP processor on CentOS 4.

Hi list, I have a problem with this stuff, i read many documents about it but i would like to know if anyone have got to resolve the problem. The point is that my vm has the clock unsynchronize, i tried many things and it seems that its work fine but im not sure. Now im using ntpd to synchronize the time but im not trust on it because it didnt work before. First, i tried the jiffies on
