Greetings, after Carsten pitched CMM2 on the kvm mini summit here is a repost of version 5 of the guest page hinting patches. The code is still the same but has been adapted to the latest git level. -- blue skies, Martin. "Reality continues to ruin my life." - Calvin.

After way to many months here is the fifth version of the guest page hinting patches. Compared to version four a few improvements have been added: - Avoid page_host_discards() calls outside of page-states.h - The discard list is now implemented via the page_free_discarded hook and architecture specific code. - PG_state_change page flag has been replaced with architecture specficic

Hi Ingo, Here''s the chunk of patches to add Xen Dom0 support (it''s probably worth creating a new xen/dom0 topic branch for it). A dom0 Xen domain is basically the same as a normal domU domain, but it has extra privileges to directly access hardware. There are two issues to deal with: - translating to and from the domain''s pseudo-physical addresses and real machine

Hi Fellas, When I connect to a domain''s console via xm console vmid I have to press an enter to get the console prompt. I am wondering if anyone else has seen this and if there is a remedy for this?

Hi Folks, To build drivers externally using linux-2.6-xen-sparse/drivers/xen/util.c, I need the symbols get_vm_area and remove_vm_area exported (they were exported previously - not any more in the latest version). Am I missing something here? -Himanshu -- ------------------------------------------------------------------------- Himanshu Raj PhD Student, GaTech (www.cc.gatech.edu/~rhim) I

This patch removes the ignored "Unconditional I/O exiting" setting in VMCS for the vmx guest since "Use I/O bitmaps" setting is being used. -Himanshu -- ------------------------------------------------------------------------- Himanshu Raj PhD Student, GaTech (www.cc.gatech.edu/~rhim) I prefer to receive attachments in an open, non-proprietary format.

Hi Folks, I saw some references to the same problem in mailing list but no solution. I am running a DomU with PHYSDEV access. With fedora core 4, I just changed the inittab file to not start getty''s on tty1-6, and it worked (only ttyS0 is enabled). However, same trick didn''t do it for debian. I can boot into a shell if I put init=/bin/bash on kernel command line. However,

Hi all, this patch series enables xen-swiotlb on arm and arm64. It has been heavily reworked compared to the previous versions in order to achieve better performances and to address review comments. We are not using dma_mark_clean to ensure coherency anymore. We call the platform implementation of map_page and unmap_page. We assume that dom0 has been mapped 1:1 (physical address == machine

These are the diffs against the pristine versions of arch/x86_64/kernel/[aperture.c,pci-gart.c] to better show the changes necessary to adapt those files to Xen. They were included with the patch and should not be applied again. -Mark Langsdorf AMD, Inc. --- pristine-linux-2.6.12/arch/x86_64/kernel/aperture.c 2005-06-17 12:48:29.000000000 -0700 +++

Hi all, I am using Xen 2.0.7. I have Broadcom NetXtreme BCM5704 Gigabit Ethernet (rev 02) cards which support frames greater than 1500. However when I boot into Xen and try to set the MTU to anything higher than 1500 (e.g., 4000, 8000 etc) I get a segmentation fault. After this fault, every command fails with a segmentation fault. I saw a similar bug report posted here:
