Problem installing Windows under Xen CentOS 5
by Radu Radutiu 26 Apr '07

26 Apr '07

Hi, I'm having trouble installing Windows on a fully virtualized VM on CentOS 5. The installation hangs on the blue screen saying "Setup is starting Windows". The hardware is a dual processor dual core AMD Opteron 2218 with 8GB RAM and SATA disks, CentoOS 5 i386 will all patches applied. On the same machine I have successfully installed two VM's running CentOS 5, one paravirtualized and one with full virtualization. I have tried to install Windows 2003 server and Windows XP with the same result. The installation media are iso images of the Windows MSDN DVDs. When the installation hangs at the "Setup is starting Windows" screen the virt-manager shows 25% cpu utilization for the guest ( I think this represents 100% CPU usage for the guest as it has 1 vcpu assigned out the maximum 4 vcpus). I am running the virt-manager and the virtual machine console over ssh as dom0 has no X server installed. Has anyone seen this problem? Any suggestions? Regards, Radu

It's going to be awhile before we'll be ready to upgrade that host to CentOS 5, so I'm looking at either getting a different xfs module for c4 or switching the partition back to ext3. So that I understand what I'm installing for c5, will the CentOS 5 xfs module for the mainline ("compatible with upstream") kernels be based on the in-kernel source, or will it be a replacement module (as in CentOS 4)? How about the centosplus kernels? Thanks again, Dave

Going to x86_64 may be a possibility for future hardware incarnations of the host. Dave

Error trying to mount NFS volume from kickstart in CentOS 5
by Alfred von Campe 26 Apr '07

26 Apr '07

The post section of the kickstart configuration file I have been using in CentOS4 looks like this: %post mount centosmirror:/var/www/html/ks /mnt /mnt/ks/post/post.sh > /root/post_install.log 2>&1 umount /mnt I tried to do my first CentOS 5 kickstart installation today using an identical post section, but the post install script did not run. After instrumenting the kickstart a bit, I found that the above mount command failed with the following error message: mount.nfs: Input/output error Not a very helpful error message -- any clues as to what is going on? It's a little tricky and time consuming to debug kickstart problems like these, so I thought I'd ask the list and hopefully save some time. If I execute that mount command after rebooting the system, it works just fine. Thanks, Alfred

We're running a mix of ext3 and xfs file systems on CentOS 4 workstations at our site. We have benefitted greatly from the increased performance and fast (crash recovery) reboot times that we get from xfs. We're currently running CentOS kernel 2.6.9-42.0.8.EL and xfs version 0.2-1. We have one host where we've got issues. It's a (very) busy imap server with external scsi hardware raid, dual Xeon CPUs, and 8GB of RAM (it runs the hugemem kernel). Twice now in the last few weeks we've seen it hang with the follow log message repeated many times in the logs at the time of the hang: XFS: possible memory allocation deadlock in kmem_alloc (mode:0x250) I see this error discussed in: http://oss.sgi.com/bugzilla/show_bug.cgi?id=410 ...and I'm wondering if the fixes mentioned in that bug are present in the 0.2-1 centosplus xfs drivers, or if it could get included in an xfs update for CentOS 4. Can anyone comment? Thanks for the filesystem, and the OS, it all rocks, and have a great day. Dave Thompson UW-Madison

Having trouble with FreeNX, Need help to make it work perfectly
by Kai Yang Tay 26 Apr '07

26 Apr '07

Hi thanks for the reply i am really grateful if you can tell me how to make FreeNX work like charm. I am really stuck with it, and after reinstalling the server is definitely pissing off my boss. Please help me thanks. =========================== Please let me review how my FreeNX was screwed up. After i fresh install my CentOS 5, I 'yum install freenx' and so if i am not wrong I actually install freenx 0.5.0-12 or something.... but i think ya shd be -12. Ok... so after i install freenx through yum. I follow what's on http://wiki.centos.org/FreeNX I --adduser and --passwd etc. Then copy the /etc/nxserver/client_id*.key over to my NX Client on Windows. Initially all works out. The NX session starts and i can do what i want over this remote session, and i proceed with updating of the critical updates for other apps from yum. The problem comes after i do this, right after the yum update. I choose to reboot my server. I reboot the server over the NX remote session. By going System -> Log Off -> Reboot. The NX Client's Window automatically closed (in quite a violent way with error msg). Then the server reboot. After the reboot, I try to reconnect to Server again using NX. But this time it fails with the following message. ==================================================================================== NX> 203 NXSSH running with pid: 5940 NX> 285 Enabling check on switch command NX> 285 Enabling skip of SSH config files NX> 285 Setting the preferred NX options NX> 200 Connected to address: 192.168.1.5 on port: 22 NX> 202 Authenticating user: nx NX> 208 Using auth method: publickey HELLO NXSERVER - Version 1.5.0-60-SVN OS (GPL) NX> 105 hello NXCLIENT - Version 1.5.0 NX> 134 Accepted protocol: 1.5.0 NX> 105 SET SHELL_MODE SHELL NX> 105 SET AUTH_MODE PASSWORD NX> 105 login NX> 101 User: root NX> 102 Password: NX> 103 Welcome to: XQSVR200611 user: root NX> 105 listsession --user="root" --status="suspended,running" --geometry="1280x1024x32+render+fullscreen" --type="unix-gnome" NX> 127 Sessions list of user 'root' for reconnect: Display Type Session ID Options Depth Screen Status Session Name ------- ---------------- -------------------------------- -------- ----- -------------- ----------- ------------------------------ NX> 148 Server capacity: not reached for user: root NX> 105 startsession --link="lan" --backingstore="1" --nodelay="1" --encryption="1" --cache="32M" --images="64M" --media="0" --session="XQSVR200611" --type="unix-gnome" --geometry="1280x994" --fullscreen="1" --kbtype="pc102/en_US" --screeninfo="1280x1024x32+render+fullscreen" NX> 1000 NXNODE - Version 1.5.0-60-SVN OS (GPL) NX> 700 Session id: XQSVR200611-1000-1279B1D659A32AEF7AA88D7C50CA5619 NX> 705 Session display: 1000 NX> 703 Session type: unix-gnome NX> 701 Proxy cookie: 64b824b7aa9edb0a55c6e220710fba3c NX> 702 Proxy IP: 127.0.0.1 NX> 706 Agent cookie: 64b824b7aa9edb0a55c6e220710fba3c NX> 704 Session cache: unix-gnome NX> 707 SSL tunneling: 1 NX> 1009 Session status: starting NX> 710 Session status: running NX> 1002 Commit NX> 105 /usr/bin/nxserver: line 1190: 6719 Terminated sleep $AGENT_STARTUP_TIMEOUT NX> 1006 Session status: running NX> 596 Session startup failed.

I really do not know what's wrong. When i try to connect back locally at my server. The GNOME UI is gone! I am now left with only the console logon menu. This same problem happens everytime, even with CentOS 4.4 recently. (In the past, ard DEC 2006, I did the exact same thing on my CentOS 4.4 Server, it works without any problem EVEN with the same violent exiting way, I have never have a problem connecting back to the server. But recently after i failed my installation of CentOS 5 and go back to CentOS 4.4, the problem starts to occur like what i have mentioned. And I really did what was written on the wiki, nothing i have done now is different from what i did in the past.) Please, and sincerely please. Guys, if you all know what's wrong please tell me, how should I solve it? Did I miss out something? like installing of NX Node or NX Client on the server etc? Well explained or guide is really appreciated. Thanks, really Thank You.

Update Centos-4.4 to centos-5 spents a lot of time in "restorecon"
by Joachim Backes 26 Apr '07

26 Apr '07

Hi, having running centOS-4.4 on a really fast machine (16 GB memory, 8 Opteron CPU's, SATA drives). Then making an update by using the Centos-5 CD's. The start was fast, but during update, the installer spents a very, very long wallclock time during selinx updating: for about 1/2 hour the updater runs in a restorecon/find sequence. And at the end, before the MBR is written, it spents again a long time in "install". Can somebody explain this?

Centos 5 -- Bind not
by Robert Moskowitz 26 Apr '07

26 Apr '07

Well, I just did my 2nd install. (Now doing the updates via yumex and stepping into the updates instead of risking doing it all at once.) I selected every bind related package, and then ran the BIND configuration GUI in System>Adminstration>Server Settings. Things seem to work. So I uninstalled and reinstalled on my new DNS server and it looks like I can proceed on the install.
