Hello everyone! With the completion of our first few release candidates for 4.2, it''s time to look forward and start planning for the 4.3 release. I''ve volunteered to step up and help coordinate the release for this cycle. The 4.2 release cycle this time has been nearly a year and a half. One of the problems with having such a long release is that people who get in features

I''m trying to compile pvscsi out-of-tree, and I''m getting an error that set_phys_to_machine is not defined when I try to load the module (with the warning to that effect at compile time too). This used to work fine in pvops. It seems that netfront uses that symbol in a module so I''m confused as to why pvscsi can''t... any suggestions? Is it one of the virtues of

pvscsi appears to be missing from the pvops kernel. Is there a specific reason for this or has it just not been done yet? James _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hello, does anyone knows, if and when pvscsi will be available in the official linux kernel? Kind regards. Christian _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Is anyone working on SCSI passthrough using the ''SCSI Generic'' support under Linux, eg /dev/sgX? This is how VMWare allows a VM to use SCSI devices.

I''m not sure if this is a debian thing or if debian is using an older version, but I see this in xend debug log when I try to use vscsi: cat: /sys/bus/scsi/devices/host6/vendor: No such file or directory cat: /sys/bus/scsi/devices/host6/model: No such file or directory cat: /sys/bus/scsi/devices/host6/type: No such file or directory cat: /sys/bus/scsi/devices/host6/rev: No such file or

Attached is my first attempt at getting the backend pvscsi driver (scsiback) working under the latest pvops kernel. I have tested it with the scsi frontend driver in gplpv, and have restored about 20GB of data from a HP LTO3 tape drive successfully, so it appears to be working fine. There are quite a few changes compared to the version in 2.6.18. The main change is that I get the vaddr for each

Porting the pvSCSI backend driver to the pvops kernel is turning out to be a bit harder than first thought, mostly because all the Linux routines that might be useful are written with the assumption that they would be passed a mapped buffer and they would then build an sg list out of that. pvSCSI already has an sg list, and all the routines that it makes use of have been deprecated since 2.6.18

Hi, I created an HVM type virtual machine and installed RHEL5U7 guest in it. I have assigned 7 scsi disks to the virtual machine in physical mode (using phy:), however, I see those disks are xvd and not as scsi. Is anyone aware what the problem might be ? Please let me know what kind of information do I need to post in order to narrow down to the problem. Thanks, K

Hi, I am working as a system administrator at an internet platform service provider, and I am currently seeking to re-new our Xen virtualization infrastructure for which I am mostly responsible for. Currently, we run Xen 3.4.2/3.4.3 on RHEL/CentOS 5.x (5.7) as Dom0 with CentOS 5.x pv-guests. Based on my experiments, I am currently looking into Xen 4.1.2 on RHEL/CentOS 6.x (6.2), with a

I''m updating the gplpv pvscsi driver to support the pvscsi driver in 3.3, and it''s not working properly. The first command windows issues is a ''report luns'' command, with a 16 byte buffer. The response that Dom0 gives me says that this was executed successfully. Windows then issues another ''report luns'' command that is also returned from Dom0

I have a SCSI tape backup unit attached to a kvm host managed by libvirt. Is there a way to expose the SCSI device in libvirt so I could pass the device to a virtual machine and have the virtual machine control the tape backup? Defining the device as a SCSI disk does not appear to work. In this situation, live migration is not an issue. The VM would always be tied to this host.

Hello Everyone. Well i want to write some information (not a complete backup) from my Virtual Machine to the tape drive, but the VM can''t read it. I guess i need to attach this device to the VM so it can read and write the tape driver but i don''t know how to do that, i found something similar but with a cd: # xm block-list <vm-id> –long # xm block-detach 1 5632 -f # xm

Hello! I'm having problems with udev /dev/tape/by-id/ symlinks.. it seems symlinks to tape drives are sometimes (randomly) missing after reboot. Server in question has IBM TS3200 tape library connected with 2 drives in it.. so /proc/scsi/scsi shows 3 devices: 2 tape drives, and 1 medium changer (tape library). So I should have 3 symlinks in /dev/tape/by-id/ directory.. 2 symlinks to tape

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

Hi, I am planning the roll out of a Xen dom0 running CentOS that is going to be running two DomU''s CentOS and Windows 2003 SBS. I am planning on using LVM for the disks as this (so i have read) increases i/o performance compared to image files. I need a solution to back up these machines and I have came up with the following two ideas: Idea 1, Backup the machines as images (lvm

''cat /proc/interrupts'' in a Linux PV domain shows interrupts starting at 256 and labelled as ''Dynamic-irq''. Are these available in a HVM domain, eg under Windows?

Hi all!. First of all sorry about my English it''s not very fluid. I have a small server based upon Supermicro X7DBN (Chipset Intel® 5000P) motherboard and Intel Xeon E5320 (1,83Ghz) with 4Gb of FB-DIMM RAM. The OS is Debian Lenny in dom0 (2.6.26-2-xen-amd64) and Debian Lenny in domU (2.6.26-2-xen-amd64). Xen is 3.4.2 compiled from sources. The problem comes when I need to passthrough

How should I be detecting a block-configure operation done in Dom0 in a HVM DomU? Under Debian Lenny''s Xen 3.2.1, when I execute such a command, Dom0 writes to the backend values ''params'' and ''type'', twice, but doesn''t update the ''sectors'' value to match the new device, or initiate a state change. Given that, the best I can

CentOS 4.8 Hi All: We recently had a Sony SDX-500V tape drive fail on one of our servers running CentOS 4.8. I have now replaced it with a spare SDX-500C. The problem that I am having now is that the failed drive had ceased responding to SCSI commands and we have since rebooted the system which resulted in the tape drive being removed from our current hardware configuration and the system does
