Hi, Can anybody advise me how to debug this crash? it happens when I try to start a 32 bit kernel on my 64 bit Xen system, the kernel is my own using opensuse 11.1 rc1 2.6.27.7 xen patches, the kernel works as 32 and 64 bit dom0, and as 64 bit domU PV, is there a technique to find out where in the kernel source the crash happens? i.e what line in the source code? (XEN) mm.c:707:d49 Error getting

I was giving a try to Debian Xen packages (it looks very promising by the way ; I just happen to love the ? new ? grub which handles xen images, for instance!) ; I have a box which boots correctly with xen-hypervisor-3.0-i386_3.0.2+hg9697-2 and a 2.6.16 dom0 kernel, but crashes when trying to boot linux-image-2.6.17-2-xen-686_2.6.17-7 The result is the same on two boxen (my Pentium M laptop and a

Hi, We are running a Sun Fire X2100 with 4GB RAM. We followed the how-to which we posted on http://www.debian-administration.org/articles/423, using backports packages for a k7-machine. We have one Sun Fire X2100 running a 2.6.16-16 kernel from backports, which is working fine having used the same how-to. Now we are installing another X2100 using the 2.6.16-18 kernel, which is giving some major

Hello. log of the crashing boot process: http://pasik.reaktio.net/xen/pv_ops-dom0-debug/pv_ops-dom0-bootlog-14-xen331-linux-2.6.29-rc6-crash.txt 2.6.29-rc5 based pv_ops dom0 works on the same computer.. with the same Xen version. I tried with and without pci=nomsi. adding ''noapic'' doesn''t seem to help (I need that with 2.6.29-rc5 to make it work). Any ideas

Hey, It looks like one of the patches that went in Xen 4.1 blows up. This used to work over the weekend, so I can only surmise it is one the three patches. This is with a debug=y build (which has been working nicely for the last month or more). It looks like one of the patches that went in Xen 4.1 blows up. This used to work a day ago - that is c/s 23551 worked nicely. ----- Forwarded message

Hi all, a newbie question. I''m trying to install lenny guest image (in an img file) on my lenny Dom0 by following the http://wiki.debian.org/Xen: xm create -c xm-debian.cfg install=true install-mirror=ftp://ftp.XX.debian.org/debian i created the xen-lenny-image.img using dd, format is ext3. disk is defined as (cfg file): disk =

Hello all, please tell me, is it possible (at least theoretically) to circumvent bug 622 [1] by using GRUB instead of /boot/loader to load FreeBSD kernel? Or it is silly idea: even if we bypass /boot/loader we will not be able to run FreeBSD kernel in a HVM-domain on a Intel-based host for some other reason? As far as I know, GRUB can''t load FreeBSD kernel directly, but only can

Hi, I am trying to release domU pages from page_list and xenpage_list after domU shutdown while retaining the rest of the domain information. To achieve this in __domain_finalise_shutdown i call domain_relinquish_resources. This is failing to release pages from page_list for type PGT_l2_page_tables and crashing dom0. To be specific, while testing on mini-os i saw that when

Hi All, I am not very familiar with xen details. Now I am thinking of building two privilged domain(domain 0 not driver domain) at boot time. The other question is that wether it is possible to create another domain 0 by domain-builder running in domain0? Does it make sense when domain 0 is shut down unexpectedly another domain 0 can run at once. Maybe it is absurd. I am looking forwards

These patches provide the infrastructure for paravirtualized MMU operations while at the same time cleaning up and optimizing the pagetable accessors for i386. They should be largely uncontroversial and are well tested. There are still some performance gains to be had for paravirtualization, but it is more important to get the native code base that will enable them checked in first. Zach

Hi Guys, Here is my problem... Im trying to install a Paravirtualization Guest, but Linux isnt able to recognize my disk. To install this paravirtualized guest, Im using the virt-manager and FC7_64 and a simple file as a Disk. I tried o lit of things, like specifing a ISO from nfs, http, local... I have installed in this server a FC5 (full virtualization). I have the same problem when installing

Hi, I have an opensuse10.2 and Fedora8 installed with xen with para-virtualization.I want to to guest host with Redhat Linux-9. Is it Possible or It''s only possible with Full virtualization. Please Help me On this. Thanks, Satya _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Not that I really believe it but I read somewhere (cant find it again) that microsoft was releasing paravirtualization drivers for kvm that would be adaptable to xen. Is this rumor or is this true?   I honestly can''t imagine why Microsoft would do this so I am skeptical, can anyone confirm or deny this? Provide a link perhaps?   thanks,   hikenboot
