Re: unable to access Linux HVM via xm console - Couldnot read tty from store: No such file or directory
HVM = fully virtualized. The question is, why are you using fully virtualized domUs? Why not paravirtualized (PV)?

"xm list" causing "OverflowError: int exceeds XML-RPC limits"
I am getting the following error with "xm list" on a x86_64 SLES10 Beta
system running changeset 9435:11fee62328cc. I am able to bring up DomUs
and I am able to do "xm info" without issues. But I am seeing similar
"OverflowError: int exceeds XML-RPC limits" with "xm shutdown" and "xm

hotplug vcpu problem to Centos 5.2 DomU
My dom0 is uing Centos 5.2 x64. I have just upgraded Xen from 3.3.0 to
3.3.1. After upgraded, I find that I cannot hotplug additional vcpu anymore.
I have a domU "linux1" which is a paravirtualized vm with centos 5.2. I try
to "xm vcpu-set linux1 4", it does not have any error message, but those

How to get the MAC address of a domU?
I''m creating a new domU using ''virsh create <xmlfile>'' without specifying the MAC address within the
XML file, under the assumption that the dom0 or hypervisor generates the MAC address for me. Next
I''d like to get the MAC address that was assigned to this new domU, and I don''t see a way to get
that information from the command line via virsh

xm top
Hello everybody!
I´d like to know where "xm top" gets its information from. I want to get
those informations (cpu-load, mem etc. from the domUs) and display them
with php in a browser. So are the informations stored and updated in a
textfile or something like that? Can anybody help me with this?
Regards

SELinux vs. logwatch and virsh
Hello everyone -
I am stumped ... Does anyone have suggestions on how to proceed? Is there a way
to get what I want?
The environment: CentOS 7.0 with latest patches.
The goal: I want logwatch to include a report on the status of kvm virtual computers.
The problem: When run from anacron, SELinux denies permission for the virsh utility.
Here is a portion of the logwatch output:

domU configs for virt-manager
hi all,
I can''t create domU with the virt-manager, but I''d like to use it anyway.
If I start domUs from command line (xm create ~) I can see them in the virt-manager, but they''re gone after I pause them or stop them. I assume that the virt-manager has some place where it saves config files for domUs, on linux it is usually /etc/xen/vm. I went in some obvious places

Configuring svc:/system/xvm/domains?
I''m running Xen on Nexenta Core, and I haven''t yet figured out how to
control which DomU''s are started with svcadm enable
svc:/system/xvm/domains:default.
virsh doesn''t seem to be available with Nexenta Core, so I''d rather edit
the configuration files by hand. However, I''ve found neither
OpenSolaris or Nexenta documentation on how this is

Config to set CPU affinity and distribute interrupts
Hi,
I have some problems to configure the xen I''ve installed (3.3.1). The computer is a Intel Core 2 Duo, I''m using Ubuntu 8.10 and have linux in my dom0 and winxp pro in my domU.
I have two cores and I''d like to set the affinity of dom0 to cpu0 and domU to cpu1 but I haven''t find the way of making this permanent. I''ve set cpus=1 in the domU config

xenconsole: Could not open tty `/dev/pts/5'': No such file or directory
Hi, i''m running a two dom0 nodes cluster for HA, and xen domUs running

xm list vs. xl list: more differences?
I see that "xl list" shows a domain waiting idly for console
input as "r", whereas "xm list" shows the same domain as "b".
I also see that the State field for "xl list" contains only
three characters (e.g. "r--"), whereas "xm list" shows six
(e.g. "-b----").
Is this expected/intended (e.g. "r" in xm list

On some production servers with dom0 kernel 2.6.32 pvops and xen 4.0 and

How do I see that a xVM is running as paravirtualized
I have followed a combination of instructions from this post and have been able to get an Ubuntu paravirtualized instance running under snv_96. Is there a way to "list" the fact that it is paravirtualized? For example, xm list, virsh list, etc.

qemu disk cache mode
Hi all,
I can''t find any good talk about this subject and would like some insights
and advices on the cache side in xen.
I discovered that a domO power outage can lead to a severe filesystem
corruption of the domUs. The domO is a dual disk dell server with a PERC
controler in writethrough cache mode, the disk cache is disabled, the
scheduler in the domO/domU is NOOP, the domO is holding
