My first steps with Xen where with virt-manager, but that's been a long time ago (and it worked fine back then). I haven't looked at it since then. You simply don't need it, usually you don't want to run any X on a server. virt-install works fine, is command-line and you can either have it ask for all the parameters or you can provide all of them, so it's a "one command" installation.

[CentOS] Updated livecd building tool
I updated the livecd-tools package from version 013 to 014. This update introduces new interesting features like : - support for Xen kernel - built-in md5sum into the resulting LiveCD ISO - a new API See https://projects.centos.org/trac/livecd/wiki/GetToolset for instructions on how to get this updated toolset. Since it is a major update, I expect some bugs. I am looking for feedback from people interested in respining their own LiveCD kickstart files with the new tool.

Xen still has it's place as it's fully paravirtualized domains are still way faster then any fully virtualized setups. Plus it's the only hypervisor I know of that let's you pass-through just about any PCI device to a domU. Once VMware gets their pass-through generalized and Intel gets their next generation hardware virtualization technology mainstreamed, Xen won't have such an edge in those areas. I still have yet to see a VMware/KVM framework for cloud computing where VMs can be seemlessly transferred between hosts or even to an off-site virtualization provider. -Ross ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] problem with udev when booting kernel 5.3 release 128.4.1
Hi List, I am running a 64 bit 5.3 kernel on an intel mb and all has been well. Today I thought it would be okay to reboot so that the latest kernel was running - i.e move from 128.2.1 to 128.4.1 release. The system passes POST fine, grub passes control to the 128.4.1 kernel and the boot process is under way. after some 30 secs the system starts beeping - continuously. After I hooked up a monitor I find that udev does not come up with OK and thats when the system starts the beep beep beep .. No logs to see .. using grub to select 128.2.1 boot fine Any ideas? Thanks in advance for your words of wisdom and advice.

Sorry for thread mucking. I did not receive this email, but took it from a response. The Xen wiki describes a paravirtual install. The config file would have a line like builder="hvm" if it was fully virtualised guest. AFAIK the graphical view is just a VNC session, so I would be surprised if that managed to trash your kernel. More likely it's something that the guest is doing that is causing the issue. You could always prepare your guests on a different machine and transfer them later. Ofcourse, if you had a command of xm, that is. As I said before, I would recommend the xen list for this specific issue. As for the Xen vs whatever issue, I was disappointed when it became clear that Upstream was going to push another technology, having spent last year or two trying to learn Xen (and I am no expert, at all). Having said that, I've heard of issues with speed with KVM and I haven't had any such issues with Xen. My only issue with Xen is that the official releases are based on quite an old kernel, which is fine for CentOS, bc it is the same as the vanilla kernel. Anecdotally, a lot of issues on the xen list IMHO seem to arise from ppl using later patched kernels, which perhaps isn't the best route for stability. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

A "virt-install -p" (for paravirtualized) should get you going in an interactive fashion. If you have a kickstart file you can do a completely automated install with virt-install.

The rules of quoting and backslashes in the shell are not very uniform and can get quite tricky... Also, the \t is interpreted by sed, and AFAIK it is available in GNU sed only, so the syntax you are using above might not be very portable to other versions of "sed". If your script gets this tricky it's probably time to move to Perl, which can also do that easily in an one-liner and, in this case, might actually be more portable. (Heck, it might even be more readable!) HTH, Filipe ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
[CentOS] replacing permissions on uploaded windows files
Hello,
I've got a CentOS box and users are putting Windows long files on
it, files with " " and " - " in their filenames. I'm trying to adjust the
permissions as well as user and group membership and i'd like the changes to
be sticky. On the tld i've set permissions of 2755 and am trying to batch
convert the files and subfolders in it. I've done this:
find tld -type f |xargs chmod 644 {} \;
find tld -type d |xargs chmod 755 {} \;
Both of these are failing due to the spaces and dashes. I've tried
enclosing those {} in quotes, no good. Has anyone done this with shell or
perhaps perl?
Thanks.
Dave.

I believe what you want is 2775 and 664 (group writable), right?

Use "-print0" in find and "-0" in xargs. Also, you don't need the "{}
\;", that is syntax for "find -exec" which you are not using.
I think what you want is:
$ find tld -type f -print0 | xargs -0 chmod 664
$ find tld -type d -print0 | xargs -0 chmod 2775

You've got 'find' syntax and 'xargs' syntax hopelessly mingled. Here:
find tld -type f -print0 | xargs -0 chmod 644 --
find tld -type d -print0 | xargs -0 chmod 755 --
The "-print0" and "-0" use the ASCII NUL character as the argument
delimiter, so any legal path can be passed without being mangled.
The "--" tells chmod that none of the following arguments that might
begin with '-' should be treated as options.

This solution was specifically made for FrOSCon 2009 this weekend. I implemented most of the suggestions I made previously, and integrated both the multimedia packages (players/codecs) as well as the hardware drivers from ELRepo. To have sufficient diskspace for a CD (700MB) I had to remove some productivity applications and clean up other items you normally would keep on a LiveCD. I will make the kickstart-file available once I have finished this work. Thanks for your work, without it I would probably never have looked at it ! PS I am also planning to include your work as an example in my own presentation for FrOSCon. PS2 I had to make slight modifications to livecd-creator to make it work with a newer syslinux. A newer syslinux has various advantages. I'll probably make some more modifications to it after FrOSCon.

[CentOS] Funny stuff in SELinux -- /usr/lib/libGL.so.1.2.#prelink#.4GxqM1
Received this SELinux warning:
Summary:
SELinux is preventing ld-linux.so.2 from loading
/usr/lib/libGL.so.1.2.#prelink#.4GxqM1 which requires text relocation.
Detailed Description:
The ld-linux.so.2 application attempted to load
/usr/lib/libGL.so.1.2.#prelink#.4GxqM1 which requires text relocation.
This is a
potential security problem. Most libraries do not need this permission.
Libraries are sometimes coded incorrectly and request this permission.
The
SELinux Memory Protection Tests
(http://people.redhat.com/drepper/selinux-mem.html) web page explains
how to
remove this requirement. You can configure SELinux temporarily to allow
/usr/lib/libGL.so.1.2.#prelink#.4GxqM1 to use relocation as a
workaround, until
the library is fixed. Please file a bug report
(http://bugzilla.redhat.com/bugzilla/enter_bug.cgi) against this
package.
Allowing Access:
If you trust /usr/lib/libGL.so.1.2.#prelink#.4GxqM1 to run correctly,
you can
change the file context to textrel_shlib_t. "chcon -t textrel_shlib_t
'/usr/lib/libGL.so.1.2.#prelink#.4GxqM1'" You must also change the
default file
context files on the system in order to preserve them even on a full
relabel.
"semanage fcontext -a -t textrel_shlib_t
