This is a cherry pick of two patches that add support for guest paged out frames in the XCP 2.6.32 dom0 patch queue. First patch propagates the ENOENT returned by the hypervisor in the case of a paged out page, all the way up the call chain to the MMAPBATCH_V2 ioctl. The ioctl is mainly used to harvest those return values and retry. The second patch adds retry loops to all backend grant

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

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

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

Patrick, there following patches fix xenpaging for me. Granttable handling is incomplete. If a page is gone, a GNTST_eagain should be returned to the caller to inidcate the hypercall has to be retried after a while, until the page is available again. Please review.

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

Removing the percpu_ida code nets over 400 lines of removal. It's not as spectacular as deleting an entire architecture, but it's still a worthy reduction in lines of code. Untested due to lack of hardware and not understanding how to set up a target platform. Changes from v1: - Fixed bugs pointed out by Jens in iscsit_wait_for_tag() - Abstracted out tag freeing as requested by Bart

Hi, everyone! We google a lot, but can''t find how to config the pvscsi on our ubuntu13.04 PV on HVM.There are some links http://wiki.xen.org/wiki/Paravirtualized_SCSI http://wiki.xen.org/wiki/Xen_Configuration_File_Options And we use the config option above Configure PVSCSI devices vscsi = [ ''/dev/sdc, 0:0:0:0'' ] I pass sdc to the hvm, but in our pvhvm (ubuntu13.04)

From: Matthew Wilcox <mawilcox at microsoft.com> This is a pretty rough-and-ready conversion of the target drivers from using percpu_ida to sbitmap. It compiles; I don't have a target setup, so it's completely untested. I haven't tried to do anything particularly clever here, so it's possible that, for example, the wait queue in iscsi_target_util could be more clever, like

Hi all. We developped a pv-scsi driver that we refered Fujita-san''s scsi-driver and blkback. (see, http://www.xensource.com/files/xensummit_4/Xen_Summit_8_Matsumoto.pdf) The pv-scsi driver''s feature is as follow: * Guest has dedicated SCSI-HBAs of Dom0. * Guest can send scsi_cdb to the HBAs. * Guest recognises the HBAs from hostno of xenstore. Currentlly, We are

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

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

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

Sharing an installed copy of dovecot between several users each running a daemon within their own account (or using the same binaries for a system daemon and a user daemon) is difficult because the compile-time directory PKG_STATEDIR (typically /var/lib/dovecot) is hard-coded as the location of things like the ssl-parameters.dat file and the replicator database.
