similar to: Sun x4200 vs. Xen

I had been running CentOS 5 happily on my Sun Fire X4200 M2 systems, then I upgraded the BIOS and iLOM firmware. Now I'm running into what seems to be a fairly common problem with newer motherboards. I cannot boot unless I use the 'noapic' kernel option. If I try to boot the kernel normally, I get the error: "MP-BIOS bug: 8254 timer not connected to IO-APIC" I can

Hi there I''m busy with some tests on the above hardware and will post some scores soon. For those that do _not_ have the above available for tests, I''m open to suggestions on potential configs that I could run for you. Pop me a mail if you want something specific _or_ you have suggestions concerning filebench (varmail) config setup. Cheers This message posted from

Hello, I was testing Fedora 16 (rc2) Xen host, with included Xen 4.1.1 rpms and Linux 3.1.0 dom0 kernel. Fedora 16 PV domUs seem to work nicely. I noticed a problem with Fedora 16 Xen HVM guests though. The F16 guest kernel (Linux 3.1.0) fails with the qemu-dm emulated DVD-ROM drive.. Full HVM guest kernel dmesg attached to this email. See the end of this email for Xen cfgfile for the

Greetings all- I have a new X4200 that I''m getting ready to deploy. It has four 146 GB SAS drives. I''d like to setup the box for maximum redundancy on the data stored on these drives. Unfortunately, it looks like ZFS boot/root aren''t really options at this time. The LSI Logic controller in this box only supports either a RAID0 array with all four disks, or a RAID 1

Hello I am running opensuse 11 on a Sun x4150 32GB RAM 2 quad x86_64 E5450''s. It has a SAS PCI-Express LSI 3081E Host Bus Adapter (a rebranded Adaptec RAID 5805 it seems) running in a RAID 5 config. Xen in this setup is 3.2.1. The kernel is 2.6.25.18 The problem I have is that when I try to run a the xen kernel the RAID device is not found . I get messages on the console of

Hi all, I have a rhel 5.1 xen server with two rhel 3 ES hvm guests installed. Both rhel3 guests use an internal xen bridge (xenbr1) which it isn''t binded to any physical interface host. On this bridge throughput it is very very poor, only 2.5 Mbs. How can I increase this throughput??? Many thanks. -- CL Martinez carlopmart {at} gmail {d0t} com

Hi, some more info which I collected during physically accessing the machine while rebooting. I was suprised that while it was not able to do anything it was not a ''static'' kernel panic, but the following text was scrolling continously thru the screen: """ ata3: port reset, p_is 1 is e pis 1 cmd c017 tf 50 ss 113 se 0 ata3: status=0x50 { DriveReady SeekComplete }

Hi: I have a problem with XEN and networking on a AMD Turion64 laptop. The network interface is a Broadcom NetXtreme BCM5751M PCI express. I have the problem on both RHEL5 and SUSE SLES 10 but I am troubleshooting it on RHEL. When I run the standard kernel, the eth0 interface works absolutely fine with either DHCP or a static IP address. When I boot the XEX kernel, eth0 fails to

Hi, Live migration was working well for me with 3.1. Recently I move to 3.2, and now live migration does not work anymore.

Hi there, It is my understanding that blktap2 has been removed from the built of xen-hypervisor-{i386|amd64} because of the OpenSSL licensing and its incompatibility with the GPL, but apparently it is possible to not use OpenSSL at all. What is your thoughts about this? Could blktap2 support be added? Should it be packaged separately and be sent to non-free? Thomas -------- Original Message

I am writing this email in the hopes of getting some advice from Xen users. My main concern is performance and stability. Before I get any further, let me explain the environment: 1. I am using redhat enterprise linux 5 with the xen kernel (2.6.18-8.1.1.el5xen). This is on a Sun X4200 with two dual core AMD processors, 16Gb of RAM, a Sun StoredgeTek 3320 attached to the X4200,

Hello , I have installed RHEL 5 on a Intel Core Duo processor based board. It has 1 GB of physical memory. I have a driver which uses the memory reserved at the top of the high memory. Well this driver worked fine on all the previous versions of RHEL/FC and also with RHEL 5 with virtualization disabled. But with virtualization enabled , the ioremap to the memory reserved at the top of high

Hello List, I''ve got Xen running on RHEL 4 using the mv /lib/tsl /lib/tsl.disabled short cut but its killing my performance, mouse hardly moves and takes an age for anything to render. There''s an rpm on the wiki to install a xenglibc for RHEL 3 and I''m just curious can I use this on RHEL 4? Failing that anyone have any advice on where to look for

So far, I''ve only found references to success under VMware. But has anyone managed it, with either the open source or commercial versions of Xen? I like Xen and have worked with it extensively for RHEL and CentOS, but it could save me a whole lot of hardware money if I can decommission some OpenServer hardware and store working OS''s under virtual images.
