Hi, i have seen a post with the same title, but didn''t help a lot -it mentioned, that the image was for LVM, which i don''t think is my case. I downloaded the debian31 image from http://jailtime.org. Initially, i had some problems and changed the configuration file a little. Here it is now: ----------- kernel = "/boot/vmlinuz-2.6-xenU" memory = 256 name =

Hello, I have migrate my running Samba-PDC Setup with LDAP from Debian Etch to Ubuntu Hardy Server 8.04. LDAP ist running correct. Samba Setup ist working right, but acces to Users Home has a poor performance. Access to a "PUBLIC" Folder is much faster! Bug Report: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/299306 The Usershare Folder: drwxrwx--T 2 root sambashare 4096 Nov

This bug report can be closed.... The Problem was an error in mapping user and group ID to the LDAP UID/GID! I have set the right UID/GID in the smb.conf with uid map = 10000-20000 gid map = 500-600 -> no errors in config!!

Hi, Looks like this patch broke automated builds due to a lack of a matching line in the defconfigs. Below is a patch that makes this a module for xen and xen0, unconfigured for xenU. That might not be the best thing here however. Thanks kurt Signed-off-by: Kurt Hackel <kurt.hackel@oracle.com> ===================================================== diff -r cd744c5ec950

Since we are using the m2p_override we do have struct pages corresponding to the user vma mmap''ed by gntdev. Removing the VM_PFNMAP flag makes get_user_pages work on that vma. An example test case would be using a Xen userspace block backend (QDISK) on a file on NFS using O_DIRECT. The patch should be backported back to 2.6.38. Signed-off-by: Stefano Stabellini

From: Jason Gunthorpe <jgg at mellanox.com> gntdev simply wants to monitor a specific VMA for any notifier events, this can be done straightforwardly using mmu_range_notifier_insert() over the VMA's VA range. The notifier should be attached until the original VMA is destroyed. It is unclear if any of this is even sane, but at least a lot of duplicate code is removed. Cc: Oleksandr

Since when we are using the m2p_override it is not true anymore that the mmap''ed area doesn''t have corresponsing struct pages. Removing the VM_PFNMAP flag makes get_user_pages work on the mmap''ed user vma. An example test case would be using a Xen userspace block backend (QDISK) on a file on NFS using O_DIRECT. The patch should be backported back to 2.6.38.

I''m just a newb at xen, but here''s what I can tell you from my own experience getting xend going: The appropriate features for evtchn and gntdev must be turned on in the kernel. Check /boot/config-`uname -r` to see if CONFIG_XEN_GNTDEV=y and CONFIG_XEN_DEV_EVTCHN=m (maybe y is okay? I''m not sure). Just do it to verify that the precompiled kernel has the options you

copy_to_user() returns the amount of data remaining to be copied. We want to return a negative error code here. The upper layers just call WARN_ON() if we return non-zero so this doesn't change the behavior. But returning -EFAULT is still cleaner.
