Hi, V6: The only change from V5 is in patch #6: - changed comment to reflect autoxlate - removed a redundant ASSERT - reworked logic a bit so that get_page_from_gfn() is called with NULL for p2m type as before. arm has ASSERT wanting it to be NULL. Tim: patch 4 needs your approval. Daniel: patch 5 needs your approval. These patches implement PVH dom0. Patches 1 and 2

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

Hi, I find that after I use xm mem-set to change the current memory allocation of a dom, the MemTotal in /proc/meminfo will give the current allocation. In my understanding, the balloon driver simply alloc / free pages, so the MemTotal should not be changed. Only the free memory will be affected. In normal linux, the value of MemTotal comes from "totalram_pages" defined in

I just built 4.3.0 in order to get > 2GB of RAM in domU with GPU passthrough without crashes. Unfortunately, the same crashes still happen. Massive frame buffer corruption on domU before it locks up solid. It seems the PCI memory stomp is still happening. I am using qemu-dm, as I did on Xen 4.2.x. So whatever fix for this went into 4.3.0 didn''t fix it for me. Passing less than 2GB

Changes from v3: - mini-os configuration files moved into stubdom/ - mini-os extra console support now a config option - Fewer #ifdefs - grant table setup uses hypercall bounce - Xenstore stub domain syslog support re-enabled Changes from v2: - configuration support added to mini-os build system - add mini-os support for conditionally compiling frontends, xenbus -

This patch series is a reworking of a series developed by Mukesh Rathor at Oracle. The entirety of the design and development was done by him; I have only reworked, reorganized, and simplified things in a way that I think makes more sense. The vast majority of the credit for this effort therefore goes to him. This version is labelled v13 because it is based on his most recent series, v11.
