# HG changeset patch # User Ian Campbell <ijc@hellion.org.uk> # Date 1354011148 0 # Node ID 3174dc24e3efb0c5b964c244dbfb0218a03a38cf # Parent 541b0e1a36c86db5df04988dd4ade5430776a7f2 xl: xl.conf(5): correct advice re autoballooning vs. dom0_mem. The advice was backwards, you should really disable autoballoon if you use dom0_mem. Also add a reference to the command-line docs.

This should have gone here and not to #706233. Patch will obviously need rebasing by now... ----- Forwarded message from Ian Campbell <ijc at hellion.org.uk> ----- Date: Fri, 16 Aug 2013 14:56:49 +0100 From: Ian Campbell <ijc at hellion.org.uk> To: 706233 at bugs.debian.org Cc: control at bugs.debian.org Subject: move core dumps to /var/lib/xen/dump X-Spam-Status: No, score=-4.9

Hi list, I try to understand memory ballooning. I have a xen server (kernel 2.6.27.54-0.2-xen) with 32 gb total memory. A domU has been started with "memory=4096" and "maxmem=8192". This is the status of the balloon driver in the domU: test:~ # cat /proc/xen/balloon Current allocation: 4194304 kB Requested target: 4194304 kB Minimum target: 565248 kB Maximum

Package: xen-hypervisor-4.0-amd64 Version: 4.0.1-2 Severity: normal -- System Information: Debian Release: 6.0.1 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.32-5-xen-amd64 (SMP w/4 CPU cores) Locale: LANG=en_CA.UTF-8, LC_CTYPE=en_CA.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash

I have a xen server setup that I want to install a lot of vms on if possible. The vms will have no utilization for the most part; and brief utilization when active. The server has 2GB of RAM. We were running into a problem were the dom0 would not let us add anymore vms because we were out of physical memory. I have started to read about memory ballooning and hoping someone could point me

tags 706233 +patch thanks This is somewhat more FHS compliant IMHO. commit 7d171826bc97bf5f3f2019fc32c1ca85b49de7c9 Author: Ian Campbell <ijc at hellion.org.uk> Date: Fri Aug 16 14:54:42 2013 +0100 * debian/patches/tools-core-dump-dir.patch: Switch tools to dumping to /var/log/xen/dump by default. * debian/xen-utils-common.dirs: Ensure /var/lib/xen/dump is created *

The changeset ''12803:df5fa63490f4da7b65c56087a68783dbcb7944f8'' added a new hypercall XENMEM_set_memory_map for specifying the e820 mapping. There was a small bug in the userspace side of this change though - the e820 mapping was specified based on the ''memory_static_min'' domain info parameter which means the memory map size is clamped to the value

hi, there is something, what i don''t understand.

Using the 3.0.2-2 hypervisor supplied by XenSource, it works just fine. Because the install process overrides other things, reverified with debian hypervisor afterwards and symptom continues.

I'm using a tarball from http://bits.xensource.com/oss-xen/release/4.1.0/xen-4.1.0.tar.gz It seems Thomas used the tools/ioemu-qemu-xen subdirectory as source for xen-qemu-dm. At a first glance I didn't notice debian/mypatches/add-rules.patch: it adds Rules.mk from the tools

Hi, First of all, thanks for your help. I have made some test with this results debian testing with xen 4.4 can run if we add mmcfg=0 as boot options to kernel boot parameters !!! Remember that with xen kernel <=4.0 works perfect without to add mmcfg=0 I have tried to install citrix xenserver 5.6 and works perfect (remember that this is xen 3 branch) Also we have tried to install xenserver
