I sent the following to xen-users, but thought I'd ask the Fedora
I am running the OpenSSL s_server/s_time benchmark between two DomUs. The
two DomUs are running on separate machines, and they are the only
unprivileged domain running on their machine. Both machines have dual
core AMD processors, with Dom0 limited to one core using dom0_max_vcpus=1.
I am using xen-4.0.1 and Xen kernel-220.127.116.11.
When I run
openssl s_time -connect 18.104.22.168:443
No CIPHER specified
Collecting connection statistics for 30 seconds
This command makes SSL connections and prints 't' to indicate success.
The t's are printed quickly at first but then they pause. After a pause,
things continue again and repeat. It seems that s_time processes for
approximately one second and then pauses for three seconds.
The same thing happens when I run s_time in Dom0 but s_server in DomU
(on the separate machines).
When I run both s_server and s_time in Dom0 (on the separate machines),
there are no pauses.
Also, when I run s_time in DomU and s_server in Dom0 (on the separate
machines) there are no pauses.
Does anyone have any idea what could be going on?
I am running xen-4.0.1 on Fedora 14 (x86_64) with kernel 2.6.38-0.rc4. All xen
modules are loaded correctly.
# lsmod | grep xen
xen_netback 24607 0 [permanent]
xen_gntdev 9063 0
xen_evtchn 5179 1
xenfs 9917 1
I have created images of Ubuntu (maverick) & Debian (squeeze) using
xen-create-image. However, when I try to boot the images using xm, I am getting
the following error (for both Debian & Ubuntu):
# xm create /etc/xen/debian01.cfg -c
Using config file "/etc/xen/debian01.cfg".
Error: Device 51714 (vbd) could not be connected. Path closed or removed during
hotplug add: backend/vbd/16/51714 state: 1
SELinux is turned off. The disk section of cfg is as follows:
root = '/dev/xvda2 ro'
disk = [
I am stuck at this for weeks, and have almost exhausted google hits.
Any help would be highly appreciated.
Thanks & Regards,
I have a new kernel (2.6.38-0.rc4.git3.1.xendom0.fc15) at
http://koji.fedoraproject.org/koji/taskinfo?taskID=2833991 . This uses the
Konrad's devel/next-2.6.38 branch (from
http://git.kernel.org/?p=linux/kernel/git/konrad/xen.git ), as I have been
having trouble which Jeremy's xen/next-2.6.38 branch.
It has the revised xen-netback patches, so doesn't need the hack to
/etc/sysconfig/modules/xen.modules that the previous kernel needed to
avoid backtraces (indeed the hack stops xen-netback loading with this
kernel as the netback_kthread parameter has been dropped).
Has anyone else noticed that "xl create DOM -c" does not work when using
$ sudo xl create Client.conf -c
Usage: xl [-v] create <ConfigFile> [options] [vars]
Create a domain from config file <filename>.
-h Print this help.
-p Leave the domain paused after it is created.
-c Connect to the console after the domain is created.
So the documentation states that "-c" should accepted, but the program
does not accept it.
I am trying to install XEN on Fedora 14 with linux kernel 2.6.35 or above as
Can some body give link for XEN 4.01 RPM for Fedora 14 with linux dom0
kernel 2.6.35 and above.
I try to search on link given in email Kozi but I am not able to downlad
it. I am able to download
Xen 4.01 but not kernel.
Can some body also have some tutorial for installing XEN on Fedora 14 will
