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

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 _______________________________________________

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

Hello, I am running a functional Xen 4.0 platform. The objective is the project I am currently running is to replace 4 VMWare ESX by 4 Xen 4.0 hypervisors. I have been able to reproduce all the core VMWare features in Xen (but better of course =D) except memory overcommitment. I know this feature has been included since Xen 3.3 but I have found almost no information about it. When I try to

Hmmm... It appears I never posted the corrected version of this patch so it never made it upstream. See: http://lists.xen.org/archives/html/xen-devel/2011-11/msg00587.html http://lists.xen.org/archives/html/xen-devel/2011-11/msg02145.html It would be good if this very minor fix was also applied to 4.2 (and, if possible, 4.1). Thanks, Dan =================== The program xen-tmem-list-parse

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

XEN_DOM0 is a silent option that has been automatically selected when CONFIG_XEN is selected since 6b0661a5e6fbf. If this option was changed to a menu configurable option then it would only give users the ability to compile out about 100 kbytes of code. As that option makes little sense to choose, and the option isn''t menu selectable anyway, then we can clean up some code by simply

Does anyone have any information on how to use DUNDi precaching? Mark Spencer made a post 2 years ago where he hinted it may be possible to configure DUNDi such that you could centralise your DUNDi registration info by using precaching, instead of having each DUNDi peer meshed with every other one... http://lists.digium.com/pipermail/dundi/2004-October/000189.html However, it seems that no

Hi. doveadm -D fetch -u login \ 'imap.envelope imap.bodystructure size.virtual date.received' '*' according to mail archives allows to regenerate indexes and precache specified headers for imap usage.
