KVM problem after update to 5.6
Hello, after updating to Cents 5.6 and so to kvm-83-224
my KVM virtual machines qemu qcow2 based images do not start anymore.
Looking at VM console the error message is that VM media is not bootable.
Going back to previous KVM version kvm-83-164 from Centos 5.5 they works
again.
What's wrong with qemu images ?
anyone has an idea on how to fix the problem ?
thanks

Hi,
I''m doing some test on a network 10 gb nics and xen
with version 3.1 i''m measuring 2.5 gb/sec from domU to an external physical machine with iperf.
switching to 3.2 has reduced the measured performance to 40-50 Mb/sec.
did anything change in the network interface?

Centos6 ipsec troubles
Hello,
it looks like the usual way to do ipsec on centos5 won't work anymore on
centos6
I installed ipsec-tools but an interface type IPsec is not recognized by
the kernel
ifup ipsec0
Device does not seem to be present, delaying initialization.
I am not planning to use the awful OpenSwan, I Want to sue the Kame
implementation which was working fine on CentOS5

Xen and networking.
I have a beefy machine
(Intel dual-quad core, 16GB memory 2 x GigE)
I have loaded RHEL5.1-xen on the hardware and have created two logical systems:
4 cpus, 7.5 GB memory 1 x Gige
Following RHEL guidelines, I have it set up so that eth0->xenbr0 and
eth1->xenbr1
Each of the two RHEL5.1 guests uses one of the interfaces and this is
verified at the
switch by seeing the unique MAC addresses.

hwclock problem
Hi.
I run peridocally (from cron) on all of my machines
30 * * * * root /sbin/hwclock --systohc
All of those machines in question take their time via NTP
from the same local server, and that server gets its time
from a ntp pool.
Now I had to reboot a couple of them two days ago and to my surprise
all had problems with the time upon booting.
Here are the important files:

Icecast Logs Timestamp in UTC
Hello,
I'm having a major problem with the timestamps in both the Icecast access.log and error.log. The timestamp on the logfiles themselves is accurate, but the logging of the various connections to my streams is in UTC. No matter how I try to configure the hwclock or the system clock, the log timestamp is always UTC, which is 8 hours ahead of my current time zone. I've even tried

Strange issue with system time being off
Hi all,
I am having an issue with some older CentOS 5.3 servers. Every time
the server boots, it gives the error "Cannot access the hardware clock
by any known method", and then promptly sets the time 5 hours behind
the hardware clock, down to the second.
After the system is up. "hwclock" works fine. hwclock --debug does not
show any error at all.

Timeserver sending wrong time to Windows Clients
Help Andrew! and whoever else..
I have a Linux Mandrake 7.2 box with Samba 2.07 acting as a timeserver
for our local lan. We are in the CST timezone. All windows boxes sync
thier time from the Linux box via: net time \\Nemesis /set /yes. I would
like to have xntp keep the clock on the server updated.
Problem:
ntpdate and xntp work great at setting the Linux box hardware clock to
GMT.

Hi,
the date jumps within 30 seconds to a wrong value. ntp service is
stopped at the beginning.
Whereas hwclock seems more precise.

monitor option in libvirt ?
Hello,
I woudl liek to start qemu-kvm with -monitor myfile.pipe options
instead of default -monitor pty
Anyway I have not found any way to tell libvirt (using virsh) that I
want to set a specific
-monitor option to the qemu-kvm command line.
How can I do this ?
I do not want to start manually qemu-kvm because in this way I will
loose the libvirt VM management

libvirt security update CVE-2011-1146
Hello,
I have seen that package libvirt-0.8.2-15.el5_6.3 on CentOS 5.6 which
addresses CVE-2011-1146
<https://www.redhat.com/security/data/cve/CVE-2011-1146.html> vulnerability
is not yet available while for example it is on Scientific Linux.
Is there any particular reason why the above rpm update is still not
available on mirrors ?
thank you

Problem in linux domU re: /dev/rtc and hwclock
Hi all,
One of our domU VMs (CentOS 5.6 x86_64) runs a cobol application,
which in turn called ''clock'' to get timestamps. Changing this is
non-trivial.
When I try to call ''clock --debug'' I get:
[root@vm0010 ~]# clock --debug
hwclock from util-linux-2.13-pre7
hwclock: Open of /dev/rtc failed, errno=19: No such device.
No usable clock interface found.

security = domain / security = server
I understand that the difference between "server" and "domain" mode is that
in "domain" mode"Samba fully uses the domain capabilities. He behaves like
another NT Server or Windows 9x do by participating in domain trust
relationships."
Could someone please explain me

I suggest reading the man page for 'hwclock'. Namely, the --utc
option. If you don't tell your system that the BIOS is stored as UTC,
then it will assume it's
