On Xen-3.3.0, domain0 Megaraid SAS (SAS 1068 controller) driver is not loading correctly if vtd support in Xen is enabled. It fails at the point of initializing firmware. I wasn''t seeing this error with Xen-3.2.2-rc3 (Unstable version), though with vtd disabled in Xen-3.3.0, it is working. Looks like a degrade problem. Any clues? Thx, Venkat

To me, the advantage of nvme is that it provides more than decent performance on unmodified Windows guests, and thanks to your vendor extension can be used on Linux as well with speeds comparable to

Package: xen-hypervisor-3.4-amd64 and linux-image-2.6.32-5-xen-amd64 Version: 3.4.3-1 and 2.6.32-15 Hello all, GRUB-PC does not automatically populate Xen related parameters in /boot/grub/grub.cfg so I added them manually (see below). All the packages involved on my Dell PowerEdge R710 running Debian GNU/Linux Squeeze AMD64 are from the Squeeze repository. There are four (4) 1TB SATA HDD

I have a perc5i (and perc5e) raid controller in my poweredge 2970 running centos 5.5. The RAID controller config is set for write-back policy, which I can confirm by checking in OpenManage. I also called Dell and ran their reporting application and had them double check to make sure everything looks OK hardware wise and they confirm that it does Yet when CentOS boots is appears to use the

Hi Alex, I've been playing around with VFIO and megasas (of course). What I did now was switching between VFIO and 'normal' operation, ie emulated access. megasas is happily running under VFIO, but when I do an emergency stop like killing the Qemu session the PCI device is not properly reset. IE when I load 'megaraid_sas' after unbinding the vfio_pci module the driver

Hi all, we got a new test system here and I just also tested btrfs raid6 on that. Write performance is slightly lower than hw-raid (LSI megasas) and md-raid6, but it probably would be much better than any of these two, if it wouldn''t read all the during the writes. Is this a known issue? This is with linux-3.9.2. Thanks, Bernd -- To unsubscribe from this list: send the line

Hi, I just came across this box [0] (McKay Creek). Seems to be exceptional building material for ZFS based NAS/iSCSI unit. I especially liked the two extra system disks hidden inside the box ! Any one have an experience with these ? [0] http://www.intel.com/design/servers/storage/ssr212mc2 -- Regards, Cyril
