I notice that since upgrading to the CentOS Xen 3.2 package the command "xm console" appears to hang. Only when I hit enter it shows me the login prompt. If I don''t do that it hangs indefinitely. Also, it prints a dmesg-like output before showing the login prompt now. If I hit enter too fast it may still be in the middle of this output and I have even seen it then hang

I''m trying to get DHCP working with DomU clients. I don''t want to use libvirtd. There''s a dhcpd on the machine and it works fine for all clients in the network, but not for DomUs. If I set a static IP on the DomU all networking for them is fine, so there''s no general networking problem. I use the xen 3.2 packages for CentOS on CentOS 5.1. There was a public

The new virtual machine manager in Centos 5.1 displays some weird behavior here and I assume it's because the UUID of one running VM is the same as of a VM that is shut down. I used the same config file template for creating all my test VMs, so several have the same UUID. Didn't produce any problems with xm. But the new VM manager in Gnome shows active and inactive VMs and identifies

Just starting and playing around with Xen on Centos 5. I created a new VM (para-virtualized) with the Virtual Machine Manager, installed Centos 5 minimal on it, rebooted after successful installation. The VM console vanishes on shutdown and that's it. The VM id vanishes from the VM Manager and there's no way to get it back. It looks like the new VM doesn't exist. xm list shows only

With the upgrade to 5.1 I get new behavior when I "open" the console from vm manager. Before 5.1 it showed the console login message like on a physical machine. However, with 5.1 I get a window that wants a password and has a checkbox "save the password in your keyring". What password? No matter, what I enter there the window just hangs and when I try to close it I get a

It seems that Xen VMs are subject to file system corruption under certain conditions. I find that often when I reboot or shutdown a VM the filesystem is corrupted after that and the VM no longer usable. The xm create then fails with some Python errors and an eventual Runtime Error: unable to read filesystem No handlers could be found for logger "xend". Error: boot loader didn't

I''m using the cpufreq=dom0-kernel hypervisor kernel parameter to enable frequency scaling on the host machines for quite some time now. Since then I started to get the "Time went backwards" message on AMD machines (not on Intel machines). It''s not a big problem, so I only research it once in a while when I stumble upon it from yet another direction. There''s

I added a virtual interface eth0:1 on one of my machines and suddenly networking breaks on startup of the system (eth0 is gone) when xend starts and runs the network-bridge script. This is supposed to be fixed according to: https://bugzilla.redhat.com/show_bug.cgi I checked and the network-bridge script contains this fix. It works fine on one of my PCs when eth0:1 is added, but not on this

All of a sudden yum hangs on a Centos 4.5 (updated to the latest patch before 4.6) when I try to use it. "clean metadata" didn't help. The output of -d5 shows it gets to the point of "Reading Local RPMDB" and then sits there. The process doesn't die, but doesn't seem to do anything from that point on. strace shows this: futex(0xb76dcae8, FUTEX_WAIT, 2, NULL I

Since I updated my CentOS 5.0 host machine to 5.1 I cannot open a console from the VM Manager to a guest. Before 5.1 it opened a VM window that looks close to the VMWare window and displays the console in it, so that I can login to the console. Now I get a "pre-window" that shows a "password" textbox, a Login button and a checkbox for "Save this password in your

I have a local mirror of CentOS5 base and updates. Now with 5 having become 5.1 and in case I just want to keep on updating (at the moment) is it enough that I update the mirror of updates or do I also need an update of the base repo?

I took over a custom firewall script from my older Suse machines to my Dom-Us and it works just fine. Doing the same for Dom-0 immediately killed all traffic for the VMs. As there was no need before I had been dropping everything on the FORWARD chain. After ACCEPTing all for FORWARD my VMs are happy again. What's best practice on Dom-0, what do you do? Can I restrict the forwarding, in

Hi Guys, OK, I figured out the problem, It would seem that Comcast spelling my DNS entry wrong would do it! I have done this a zillion times, I was totally stumped as to what I would be missing this time.

make sure that your mountpoint does not have a .ogg extention with the mp3 stream, otherwise, it will try to play using the ogg plugin, and will stay at 0% buffer On Thu, 10 Mar 2005 19:45:09 +0100, Kai Schaetzl <maillists@conactive.com> wrote: > I'm new to streaming or music hearing over the wire, I still prefer my > old-fashioned stereo equipment :-) > But a friend asked me

really, it should have no extention, like /stream/1001 for the mountpoint On Thu, 10 Mar 2005 20:51:29 +0100, Kai Schaetzl <maillists@conactive.com> wrote: > Darrell Dominey wrote on Thu, 10 Mar 2005 15:31:04 -0330: > > > make sure that your mountpoint does not have a .ogg extention with the > > mp3 stream, otherwise, it will try to play using the ogg plugin, and >

I found that lm_sensors got installed because of a dependency on my first Xen VM that I updated to 5.3. lm_sensors doesn't make sense in a VM. I thought, ok let's check after the update who wants it. However: rpm -q --whatrequires lm_sensors no package requires lm_sensors (same for --triggeredby with lm_sensors or the packages below) Trying to remove lm_sensors reveals these packages:

The installed php on CentOS/RHEL is the CGI version. This means I should be able to get command line arguments with $GLOBALS[''argv''] or $_SERVER[''argv'']. That''s how the php documentation tells and how it works f.i. on Suse. However, on CentOS I get them only when I use the -n switch to php (no php.ini). The problem with -n is that php cannot find
