Odd behavior from OpenSSL benchmark
by W. Michael Petullo
I sent the following to xen-users, but thought I'd ask the Fedora
folks too.
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-2.6.32.26.
When I run
openssl s_time -connect 131.193.36.59:443
I see:
No CIPHER specified
Collecting connection statistics for 30 seconds
tttttttttttttttttttttttttttttttttttttttttttttttttttttt
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?

Error "Path closed or removed during hotplug" with xen-4.0.1 on Fedora 14 (x86_64)
by Kaustav
Hi,
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 = [
'file:/home/xen/domains/debian01/disk.img,xvda2,w',
'file:/home/xen/domains/debian01/swap.img,xvda1,w',
]
I am stuck at this for weeks, and have almost exhausted google hits.
Any help would be highly appreciated.
Thanks & Regards,

xl create ... -c
by W. Michael Petullo
Has anyone else noticed that "xl create DOM -c" does not work when using
xen-runtime-4.1.0-0.1.rc4.fc14.x86_64?
I see:
$ sudo xl create Client.conf -c
Usage: xl [-v] create <ConfigFile> [options] [vars]
Create a domain from config file <filename>.
Options:
-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.
