similar to: X86_64 and 4GB RAM using Flat Memory Model?

Hello, I originally posted this to xen-users, but someone suggested I post it here. I am having ACPI problems on a PenguinComputing Altus1600 system. It has 2x dual core Opteron 2210 processors. The system boots with a standard Debian or Ubuntu SMP kernel, with ACPI enabled. However the xen live cd, binary xen install, as well as my own custom compile of xen 3.0.4 from source will not boot.

Hi, I''ve not tried pv_ops for a long time but just got a new system (Supermicro X9DRL-iF) so decided to try 3.5.0 with the latest Xen 4.2-unstable, unfortunately the system crashes immediately after loading dom0: traps.c:486:d0 Unhandled invalid opcode fault/trap [#6] on VCPU 0 [ec=0000] I''ve tried loading both bzImage and vmlinuz (gzip compressed vmlinuz) with the same

Hello, I''m getting many "Error getting mfn" on a xen4.1.3 with dom0 3.4.11 x86_32. I thought it could be related to xen/mmu: Release just the MFN list, not MFN list and part of pagetables. http://git.kernel.org/?p=linux/kernel/git/konrad/xen.git;a=commit;h=785f62314984ea3af9dd830b020289ba2509ae69 (XEN) Freed 212kB init memory.

Hi Everyone I have sorted out the initial issues I''ve had and decided to give Xen another go. I''m trying to run Xen using kernel 2.6.37-rc3 (previous attempt with rc1 failed, and when I gave it a second go, rc3 was already out). As previously, 2.6.37-rc3 boots fine natively. 2.6.32 boots natively and under Xen as dom0, but I have reservations against running 2.6.32,

I am trying to get QNX working with Xen. I''ve going about it in a similar way as installing windows with Xen, but when I start the guest up to install the OS it hangs on the line: ''Hit Esc for .altboot.......'' If anyone has managed to get this working, or has any ideas/advice for me here it would be greatly appreciated! Bryan

Hello, I have an odd problem on a dual processor, dual core Opteron system. Obviosously it is x86_64 so should have no problem large amounts of RAM. The system has 4 GB installed (2GB on each processor). If I boot the system with a fresh install of Debian Etch it sees all the memory fine. dmesg reports: Memory: 4107008k/5242880k available (1929k kernel code, 86836k reserved, 864k data, 176k

I'm running CentOS 5.1 with all updates, and the xen kernel.

Hi Folks: I run into a problem when enabling Xen in next generation server platforms with Xen c/s is 21380. Xen reported "CPU Not responding" when booting up 32 CPUs( 2 sockets with 8 cores/16threads total). The log files belonging showed something wrong with APCI. So I added x2apic=0 in the xen grub line, but the symptom remained. However, Native RHEL5.5 can

Hi, I installed Xen 4.0.1 from source on Debian 5.0.8 and when boot my computer hardware reboots at like "Scrubbing Free RAM". I tryed to find some information here but none was helpfull to me. Anyone? I have 4GB memory and a AMD Turion II X2 M500 (

Hello! I was asking for help on the Freenode channel, and I was pointed here. I have a situation where, using xl, I can create a functional PV domU, with or without pv-grub, but I cannot access the console. Firing up xend and using xm works without trouble. Since xend and company is being deprecated, I would like to transition to using the xl toolstack. The system is an Arch Linux system

Hello, I''m trying to compile Xen unstable on NetBSD, I''ve aplied the patches from http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/sysutils/xentools41/patches/?only_with_tag=MAIN and copied the blk files from http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/sysutils/xentools41/files/?only_with_tag=MAIN (I don''t know which of these patches have been applied to xen unstable, so

?Not sure if this actually made it to the list the first time.? Here is the SERIAL output (bottom of message after your questions).? Googling the error indicates it's something people ran into a few years back but was supposedly fixed.? Any ideas? I can verify that if I REMOVE the second CPU, it boots into Xen kernel no problem.? The CPU itself doesn't matter, as I can swap either

I ran some iperf tests today and it looks like the etherbridge is the limiting factor on throughput. In the beforetime, I saw great throughput to the VMs; over 800 Mbps. With the bridge, the numbers are in the 400s somewhere. Is this the speed I can expect from the bridge? Is there some tuning I should try, or another way to get more bandwidth into the VMs? This is with xen-2.0, 2.4.27-xen0

That change converted the (wrong) assumption of contiguous nodes'' memory to a similarly wrong one of assuming discontiguous memory (i.e. each node having separate E820 table entries). The code ought to be able to deal with both, though, and I hope this change makes it so. Signed-off-by: Jan Beulich <jbeulich@novell.com> --- 2009-08-24.orig/xen/arch/x86/srat.c 2009-08-28

I'm recording TCP network throughput performance between Dom0 IP stack and all my guest domains (currently 6 running simultaneously). All guests are running simultaneously, but I only ever transmit between Dom0 and one of the DomUs while the other five are idle. When running a netperf TCP_STREAM test (netperf on Dom0, netserver on DomU) I record the following performance numbers, CPU % as

Hello list, I just got this ominous bug on my machine, that has already been seen several times: http://lists.xensource.com/archives/html/xen-devel/2006-01/msg00180.html The machine is very similar, it''s a machine with two dual-core opterons, running one of the latest xen-3.0.3-unstable (20060926 hypervisor, and a vanilla 2.6.18 + xen patch from Fedora from 20060915).
