Hi Linux kernel folks and Xen folks -- Effective July 5, I will be resigning from Oracle and "retiring" for a minimum of 12-18 months and probably/hopefully much longer. Between now and July 5, I will be tying up loose ends related to my patches but also using up accrued vacation days. If you have a loose end you''d like to see tied, please let me know ASAP and I will do my

At last year''s Xen North America Summit in Boston, I gave a talk about memory overcommitment in Xen. I showed that the basic mechanisms for moving memory between domains were already present in Xen and that, with a few scripts, it was possible to roughly load-balance memory between domains. During this effort, I discovered that "ballooning" had a lot of weaknesses, even though

Hi all, this is a non comprehensive list of missing features in libxenlight and\or xl: - xen_platform_pci flag support in VM config files; - relative paths support in VM config files; - hap support in VM config files; - -c option to xl create; - remus; - trigger command; - tmem-* commands; - sched-* commands; - usb-* commands; - scsi-* commands. In general if you execute "xm

Add tmem-* commands, did some simple tests. [PATCH 1/6]xl: Add ''xl tmem-list'' command [PATCH 2/6]xl: Add ''xl tmem-freeze'' command [PATCH 3/6]xl: Add ''xl tmem-destroy'' command [PATCH 4/6]xl: Add ''xl tmem-thaw'' command [PATCH 5/6]xl: Add ''xl tmem-set'' command [PATCH 6/6]xl: Add ''xl

This is a fourth cut of the hypervisor patch of the proposed XENMEM_claim_pages hypercall/subop, taking into account feedback from Jan and Keir and IanC, plus some fixes found via runtime debugging (using privcmd only) and some added comments/cleanup. [Logistical note: I will be out tomorrow (Friday) plus US holidays next week so my responsiveness to comments may be slower for awhile. --djm]

Hi, I have noticed that, in the code of linux/drivers/xen/balloon.c, there exists the snippet as this: static int __init balloon_init(void) { unsigned long pfn; struct page *page; if (!xen_pv_domain()) return -ENODEV; ..... } Does it means the driver will not work in HVM? If so, where is the HVN-enabled code for that? 2010-11-16 Rui Chu _______________________________________________

Folks, The second release candidate for Xen 3.4.0 is available at http://xenbits.xensource.com/xen-unstable.hg, tagged as ''3.4.0-rc2''. Please test! -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

Hi, I have allocated few order=9 pages in Xen memory space using alloc_domheap_pages(NULL,9,0) during boot time just before domain is created (dom0 = domain_create(0, DOMCRF_s3_integrity, DOM0_SSIDREF) in xen/arch/x86/setup.c). I got the following virtual addresses in xen log message- (XEN) a2k2: Virt_addr:ffff83011cc00000 MFN:11cc00 (XEN) a2k2: Virt_addr:ffff83011ca00000 MFN:11ca00 (XEN)

Prevent xl from doing any operation if xend daemon is running. That prevents bugs that happened when xl and xend raced to close a domain. Changes since v1: * Add documentation to xl man page. * Permit the execution of commands that don''t modify anything. * Indent error message.

If any new Xen developers are interested in a simple project to learn Xen development (and also Xen Transcendent Memory), it would be interesting to test this in Xen. AFAIK, the only extensive use of compression is with Transcendent Memory ("tmem"), so learning about tmem would be a useful side-effect. Thanks, Dan

__map_domain_page() *must* be matched with an unmap_domain_page(). These five static inline functions each map a page (or two), then throw away the context needed to unmap it. Each of the changes are limited to their respective functions. In two cases, this involved replacing a large amount of pointer arithmetic with memcpy() (all callers were relying on memcpy() semantics of positive/negative

Hello, I''ve hit known problem with dynamic memory management - memory fragmentation... This dynamic memory management basically does xl mem-set to balance memory. After some time of running system, xen memory is so fragmented that it is impossible to start new VM with PCI device. Sometimes it crashes during boot (no 64MB contiguous memory for SWIOTLB), or later - eg. iwlagn cannot

From: Ian Campbell <ian.campbell@citrix.com> There are many hypercalls which make no sense or which are not supported on ARM systems but it''s not all that obvious which ones we do support. So lets try and document the hypercalls which are useful on ARM. I''m not sure this is the best way to go about this, I''m open to other ideas. Signed-off-by: Ian Campbell
