Xen Balloon Driver on PVHVM CentOS6
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.
My host is Xen 4.1.2 with dom0 as 3.4.46-8.el6.centos.alt.x86_64
My guest is CentOS6.4 with kernel 3.4.46-8.el6.centos.alt.x86_64

Understanding memory ballooning
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

how mem-set / balloon changes totalram_pages
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"

pvhvm on debian
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.

Xen 4.1.2 PVHVM guest with Linux 3.1.0 network problem, empty MAC address (all zeroes)
Hello,
While testing Fedora 16 Xen PVHVM guests I noticed the following problem:
When starting F16 PVHVM guest I can see the vifX.0 and tapX.0 interfaces appear on dom0,
but after the guest kernel (Linux 3.1.0) starts and loads PVHVM drivers the
vif/tap interfaces disappear from dom0..
so the bridge in dom0 doesn''t have any vifs/taps connected to it anymore.
Has anyone seen that

Balloon driver for Linux/HVM
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?

[GIT] Xen pvhvm driver, emulated device unplug fixes
Hi Linus,
These patches make it possible to inhibit the Xen emulated device unplug
on the kernel command line (mostly "Just In Case") and renames
xen_emul_unplug=ignore to the clearer xen_emul_unplug=unnecessary.
Since it changes the name of a command line option we''d like to get it
in before 2.6.36 proper.
The third changeset is a pure cleanup which you could ignore for

I have a problem with PVHVM guests when save/restore
Hello users,
I have a problem when I save/restore a PVHVM guest.
I installed xen-4.1.2 on my server. And I run a PVHVM guest on LVM.
And my PVHVM guest is ubuntu-12.04.2-desktop.
Actually when I save a machine, it acts fine.
(Of course, when I saved it, There were some processes like movie player)
But, When I restore it, It seems more slow.
Additionally, machine finally die after a while.

configuring TE410P for four E1 PRI lines
hi,
I'm trying to configure my newly acquired TE410P card to work as 4
E1 spans. This is
supposed to be a drop-in replacement to the earlier E100P card. However,
on loading the
zaptel module it gets configured as T1 spans basically doing a 'cat' on
/proc/zaptel/1 thru 4,
it shows 24 channels per span. After this ztcfg fails saying
'ZT_CHANCONFIG failed for channel 97'.

Re: FreeBSD PVHVM call for testing
Hi,
After some more testing I thought it would be good to put this into production for my personal server. I''ve used pvhvm_v19 and built it without debugging options and installed it on a FreeBSD 9.1 system.
I''ve run into some hiccups with 9.1 user land and a 10-CURRENT kernel, but that''s all solvable[0].
My VPS has some very limited memory (256M), but I''ve

coding logic and syntax in R
Hello,
I am a beginner in R programming and recently heard about this mailing list.
Currently, I am trapped into a simple problem for which I just can't find a
solution. I have a huge dataset (~81,000 observations) that has been
analyzed and the final result is in the form of 0 and 1(one column).
I need to write a code to process this column in a little complicated way.
These 81,000
