similar to: RE: Linux PG_arch_1 conflict

Xenlinux uses a special architecture-dependent bit in the page table, called PG_arch_1 to indicate that a page is "foreign" (PG_foreign). It also apparently uses it to determine if a page is pinned (PG_pinned). Linux/ia64 (and apparently Linux/ppc and Linux/ppc64) use the PG_arch_1 bit for other purposes. On Linux/ia64, it is used to determine if the instruction cache needs to be

Hi, is there some way to trigger sysrq from the serial console in xenlinux? With native linux it works by sending a break + sysrq letter, in xenlinux it doesn''t work that way though ... cheers, Gerd -- panic("it works"); /* avoid being flooded with debug messages */ _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com

Hello Xen Users, I am facing a problem getting my installation of XEN boot up on a Red Hat Linux Guest OS. What''s happening is that the grub loader tries to install Xen but after a while it crashes and starts rebooting recursively. I have tried both the entries listed below. I am using the following entries in the grub.conf file: title Xen-bhatia 3.0 / XenLinux-bhatia 2.6.16

Is now time for accepting new features? Here''s updated S3 patch set for Xen/dom0, based on latest 15017 changeset. Comments welcomed. ========================================= Changes since last version: - Rebase to latest 15017 - X86-64 support - Force lazy context sync before cpu goes down - S5 poweroff support - Several bug fixes observed when running on different machines

hello, I am attempting to compile a Dom0 CentOS 5.2 guest from source, using XenLinux 2.6.18.8 with a Xen 3.2.1 hypervisor. I am able to compile the Dom0 kernel, but when I attempt to boot into it, I receive the following messages: mount: could not find filesystem ''/dev/root'' setuproot: moving /dev failed: No such file or directory setuproot: error mounting /proc: No such

With this patch, x86 and x86-64 share ioport.c, fixing LTP iopl and ioperm testcase failures (on both). We found an iopl testcase failing even on x86 xenlinux. Now x86-64 xenlinux should have the same results regarding the LTP testcases (as far as we tested).

Is it possible to disable one of the (real) Ethernet interfaces from Xen so that Domain 0 doesn''t see it? I.e. when the Domain 0 XenLinux boots up it only has eth0 although there are actually two NICs in the machine. Would it be possible to do this using the "nics=" parameter? I know this can be done for doms>0 but get the impression Domain 0 is different. Alternatively

Hi, all, Attached patch set is the first support to S3 (suspend to ram) on Xen environment. We know that 3.0.5 is feature freeze now, and thus this version is just for trial and review first. X86-64 is to go (failed to compile), but we have a preliminary support in house which is however on an old version and not very stable yet. It''s supposed to be out with next version. Totally

Hello, my problem is that after installing Xen and configuring menu.lst the new Xen-Kernel doesn''t start. I''m getting a message that the Kernel can''t find the root partition. I''m using the XenLinux 2.6.11 kernel my menu.lst entry looks like this tilte Xen 2.0 / XenLinux 2.6.11 kernel /boot/xen.gz dom0_mem=64000 module

Odd question I know. I am looking for source for as recent a kernel as possible running the old style xenlinux/xenified kernel (i.e. capable of running the xen3.3.x hypervisor). Any ideas where I can get this - preferably in git form? I think Stefano Stabellini had something that worked up to 2.6.36 (from memory). And yes, we would all prefer all our customers moved to xen4 but this is difficult

Hello. =) I''m having a bit of trouble with my nfs xen installation and have spent much time trying to research/figure out this problem with no luck, so I''m hoping someone might be able to help me here. =) I''ve successfully installed xen 3.02 on Linux RH4 on my Sun single proc opteron v20z server. I''ve installed what I believe to be a base Linux OS on a

Hello list, I cannot get make-kpkg to build a Xenlinux type kernel into a Debian kernel binary on my Debian Squeeze x86_64 system. I am using GNU/Linux kernel sources tree (2.6.34.4) with Xen patches for this custom kernel. I am trying to use the make-kpkg command to build a working linux-image-2.6.34.4-xen-amd64 package for my system. The sources are vanilla (available from kernel.org) with

Hello, http://pasik.reaktio.net/xen/patches/xen-pvscsi-drivers-linux-2.6.32.27-pvops-v01.diff This is the first version of Xen PVSCSI drivers, both the scsiback backend and scsifront frontend, ported from Novell SLES11SP1 2.6.32 Xenlinux kernel to pvops xen/stable-2.6.32.x branch. At the moment it''s *only* compile-tested with the latest xen/stable-2.6.32.x git kernel as of today

Hello, I''m trying to build XenLinux 2.4.30 on debian.

Dear all, When I debugged the execution performance of an application using strace, I found there are some system calls like open and stat64 which run faster on XenLinux than the standard Linux. The following is the output of running "strace -c /bin/sh -c /bin/echo foo" on both systems. An open call runs averagely 109 usec on standard Linux but only 41 usecs on XenLinux. An stat64

Hi. I am trying to install xen 2.0.5 and am having problems getting the xen kernel to boot. It seems to come up, recognize the PCI bus info, the CPU, memory, and such, and then halts when it gets to trying to mount NFS. It then asks for a boot floppy. My guess is that it is not finding the / partition. The actual kernel panic string, I don''t have because the screen blanks so
