Hi, I''ve been trying to boot stefano''s minimal dom0 kernel from git://xenbits.xen.org/people/sstabellini/linux-pvhvm.git 2.6.36-rc1-initial-domain-v2+pat On xen-unstable, I get the following WARN_ON()''s from Xen when bringing up the NIC''s, then the machine hangs forever when trying to login either over serial or NIC. (XEN) Xen WARN at msi.c:649 (XEN) ----[

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

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

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

Running with Xen option dom0_mem=6G and kernel option mem=8G, I would have expected that I would see the system with a 2G balloon right after boot. However, the balloon is empty. Briefly looking at this, it would seem to me that, with all pages being reserved when the system starts and only the populated ones getting the reserved status cleared in __free_pages_bootmem(), the condition to put pages

Hi, I am sending this e-mail once again because it probably has been lost in abyss of Xen-devel/LKLM list. Here is the second version of memory hotplug support for Xen guests patch. This one cleanly applies to git://git.kernel.org/pub/scm/linux/kernel/git/jeremy/xen.git repository, xen/memory-hotplug head. Changes: - /sys/devices/system/memory/probe interface has been removed;

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

hello, I know this not quite a xen problem but im sure a fair number of people are using debian for their dom0 and maybe have some insight into this. I have a large number of dom0''s running squeeze and for a long time i was hoping for pvhvm to make into the official debian xen packages and recently during some periodic updates I noticed pvhvm working after a kernel package update. Now

Hi List, I''m trying to work out the balloon driver on CentOS6 HVM but it seems to be not working with default 2.6.32 or newer 3.4 kernel. Does balloon driver work on HVM linux guests with Linux Kernel 3.4 from centos repo ? PV is fine and is able to balloon. Thanks. _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org

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).
