I notice that IO performance is notably slower than the stock RHEL kernel; about 1/2 overall write performance. I can trigger the bug

Hi all, I posted the following message in the devel list without successful, expect here have a little more luck ;) Just add that testing the same setup on a VMware (I mean, not in a physical hardware) all go fine.

After two days of banging on this issue I have reached two resolutions. 1. Flashing the 3ware card to latest firmware (3.08.00.016) seems to have solved it with all kernel versions. This is highly recommended that

Hi list, I''ve read about recent efforts to push pv-on-hvm drivers to Linux mainline and I''m curious to know the cause for this. What''s the advantage over using pv_ops directly and booting the kernel paravirtualized? Are there plans to move Linux domUs closer to the KVM way (from an architectural point of view)? Hope you can help. Regards, Markus

Hello all, I''m getting stucked with debian and Xen 3.0.2 Problem is that during boot with xen kernel system said: mount: unknown filesystem ''devfs'' and then Unable to open initial console /dev/console And reboot...

We were about to give up on Xen as all of our servers use 3ware cards...all is good now! _______________________________________________ Xen-devel mailing list

Hi, At the time of writing this mail, a few days ago, I couldn''t access the lists, so my apologies if this mail is received duplicate. I recently bought a new server with a 3Ware 8006-2LP controller to run Xen on a Debian linux distribution: - Server: ASUS RS120-E4/PA4 - Debian Release: etch - Architecture: 32bit / 686 - Memory: 8 GB - Disks: 2x Hitachi HDT725050VLA360 - Controller:

My goal is to be able to install to the drive array on the 3Ware controller card. 3Ware does provide a RH WS 3 driver that I've tried to use; however, the RH Enterprise 3 WS driver doesn't work since that kernel is older than the CentOS-3.1 install kernel. I'm trying to create a centOS-3.1 installation driver disk for the 3ware 9500S card; however, I'm not having much luck.

I'm using CentOS5 64bit on a system with a 3ware 9650SE card. I installed the OS using the driver disk files provided by 3ware. It worked fine with the original CentOS5 kernel. After doing a "yum update", which also installed an updated kernel, the system didn't work after a reboot, using the new kernel. I rebooted the old kernel, moved the 3w-9xxx.ko file from

There are certian platforms which would like to use SWIOTLB based DMA API for bouncing purpose without actually requiring an IOMMU back end. But the virtio core does not allow such mechanism. Right now DMA MAP API is only selected for devices which have an IOMMU and then the QEMU/host back end will process all incoming SG buffer addresses as IOVA instead of simple GPA which is the case for simple

I have a new laptop (Dell 9400) that I am trying to work with Xen 3.0. Xen works fine, runs windows XP under HVM. But, the Xen kernel on Dom0 has a few problems with some of the hardware. The network card is a Broadcom 4400 10/100BaseT. Normally loading the b44 module gives this: Apr 28 20:07:53 ipanema kernel: [4294683.185000] b44.c:v0.97 (Nov 30, 2005) Apr 28 20:07:53 ipanema kernel:

I've been having no end of issues with a 3ware 9650SE-24M8 in a server that's coming on a year old. I've got 24 WDC WD5001ABYS drives (500GB) hooked to it, running as a single RAID6 w/ a hot spare.
