The attached re-enables the pygrub build and fixes the build with older e2fsprogs (tested on RHEL4 with e2fsprogs-1.35 and rawhide with e2fsprogs-1.38) Signed-off-by: Jeremy Katz <katzj@redhat.com> Jeremy _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

A while ago (I think at the Xummit), I recall someone saying that the structure of the files in xenlinux may change soon so that the xen-specific files would move to a subdirectory or arch/<arch> (e.g. linux/arch/i386/xen instead of linux/arch/xen/i386). Is this still planned? If so, what is the timing? If it''s in progress, I''d like to get in the loop... Thanks, Dan

Hi, in order for installers and hardware discovery programs to be able to load the right device drivers, we really want a virtual device bus in Xen, a'la power5 VIO. This "xen bus" is on the top of Jeremy's TODO list, but since I have heard rumors that some of our friends here might have (some of the) code already it would seem prudent to check whether that code could be

Three patches to clean up GDT access in Linux to make it friendly to virtualization environments. The basic problem is that the GDT must be write protected, which causes spurious overhead when the GDT lies on the same page as other data. This problem exists both for VMware and Xen; Xen actually requires page isolation, so we have implemented the most general and compatible solution. Patch 1

I've installed Sven Slezak's Notify module. He gives the follow as an example line to put into extensions.conf exten => s,1000,Notify(${CALLERIDNUM}|${CALLERIDNAME}|${EXTEN}/ sunnybook) I understand what is going on with this line but I don't know where in the extensions.conf file to put it? Thanks, Chris Griffin cgriffin@33keys.com

In OLS 2005, we described the work that we have been doing in VMware with respect a common interface for paravirtualization of Linux. We shared the general vision in Rik's virtualization BoF. This note is an update on our further work on the Virtual Machine Interface, VMI. The patches provided have been tested on 2.6.16-rc6. We are currently recollecting performance information for the new

While digging through the time code, I found something very strange in do_settime: x = (secs * 1000000000ULL) + (u64)nsecs - system_time_base; y = do_div(x, 1000000000); spin_lock(&wc_lock); wc_sec = _wc_sec = (u32)x; wc_nsec = _wc_nsec = (u32)y; spin_unlock(&wc_lock); The value "x" appears to be the number of nanoseconds, while the value

Greetings, the circus is back in town -- another version of the guest page hinting patches. The patches differ from version 6 only in the kernel version, they apply against 2.6.29. My short sniff test showed that the code is still working as expected. To recap (you can skip this if you read the boiler plate of the last version of the patches): The main benefit for guest page hinting vs. the

Hi, I have done some debugging to find out the root cause of bug 1282, which has the following symptoms with paravirtualized guests: - after a live migrate, the time on the guest can jump - after a live migrate, the guest "forgets" to wake up processes - after a domU save, dom0 reboot and domU restore, the time is correct but processes are not woken up from sys_nanosleep The problem

I have several values that need to get passed on every link on a page that lists items. For example, as the user paginates, I need to keep the current sort value, how many items to display on the page, whether to show active or inactive items in the list, etc In addition, I want them passed through edit actions as well. The user edits a record, gets sent back to the list, it should be

Unlike full virtualization in which the virtual machine provides the same platform interface as running natively on the hardware, paravirtualization requires modification to the guest operating system to work with the platform interface provided by the hypervisor. Xen was designed with performance in mind. Calls to the hypervisor are minimized, batched if necessary, and non-critical codepaths
