I have CentOS 5.5 and try to create KVM virtual machine with CentOS 5.5 as a guest. But when I exec command:
virt-install --connect qemu:///system --name test --ram 1024 --file=/var/lib/libvirt/images/test.img --file-size=10 --vnc --cdrom=/var/lib/libvirt/images/CentOS-5.5-x86_64-bin-DVD-1of2.iso --vncport=10000 --accelerate --os-type=linux --nonsparse --livecd --hvm
I just ran into a weird problem with a CentOS 5.5 64-bit server running VirtualBox 3.2.8 (I would run Vmware Server 2.0.2 if not for the well known fact that Vmware doesn't care about its Server line anymore and it doesn't run on CentOS > 5.3 without major splits). I currently have two guests in that VirtualBox setup, a CentOS 5.5 64-bit and a Fedora 13 64-bit. The CentOS 5.5 guest shows less memory available than configured. If, for example, I give the virtual machine 512MB of memory the guest OS only recognizes 380MB. If I give it 768MB it only recognizes 637MB, and so on. I don't have that problem on the Fedora guest - 1024MB configured, 1024MB available.

View 2 Replies View RelatedI'm experiencing some rather severe problems after updating my Centos 5.4 system (Virtual Xen guest). What happens is that when the system boots it complains about missing .so files which prevents about 50% of the services installed from running.
I'm suspecting that it has something to do with selinux for two reasons: 1. The first services to go down complains about the security context of some files, and 2. selinux was kinda the reason I decided to update in the first place as it was disabled when it shouldn't be (enabled in system-config-securitylevel, disabled when running sestatus).
The whole boot-sequence ends with alot of "INIT: Id 'X' respawning too fast: disabled for 5 minutes"-messages (including all runlevels) before it goes stale, and I can do nothing.
The server in question had undergone very little tinkering from my part, pretty much none at all, the only services installed after installation was apache, mysql and webmin.
Details:
CentOS 5.4 is installed on both the host and guest.
The guest runs on an lvm-partition.
I have two other vm's(also CentOS) running just fine, altough I'm a bit weary of updating them .
Attached are some screenshots of the boot-process.
I hope some one here can share some insight on this problem. It's making me pretty nervous seeing that our whole network is run by CentOS-installations (not that I'm certain that CentOS is the culprit).
Does anyone know of a way to tell the CentOS installer -not- to use LVM in a kickstart? We've been using a system that lets us define which particular drives to use during the installation as part of our deployment system. This does not work now that LVM is the 'default' in CentOS. I've looked over the options and I see how to FORCE particular LVM configurations, but I see no way to just turn it off.

I have an i5 Thinkpad running Windows 7 64-bit. VT is enabled in the BIOS. I have installed vmware server v 2.0.2 but am unable to install Centos 5.5 x86_64 as a guest OS. The steps that I followed are as follows:1. Created a new VM, specifying RHEL 5 64-bit as the intended guest OS (per vmware documentation - Centos is not available as a selection2. Downloaded all 8 iso files for Centos v5.5 64-bit3. Modified the CD/DVD drive to 'connect at power' and use an iso with the path pointing to the x86_64 iso 1 of 8When I power up the VM, the console window displays 'ISOLINUX 3.11 2005-09-02 Copyright (C) 1994-2005 H. Peter Anvin' and nothing else. The installation splash screen never appears. As a test, I downloaded the first of 7 iso files for the 32-bit version of Centos 5.5 and pointed the CD/DVD drive to that iso. In that case, the installation starts as expected. I would really like to get the 64-bit version installed and running.
View 3 Replies View RelatedWhat i want to be able to do is create a custom kickstart for my centOS 5 server. I want to create a bootable cd that I can pop in my server and basically walk away for 45 minutes and I come back and its fully installed. All the directions I have read so far tell me that I have to create a seperate ks.cfg and then I need my original centos cd to get it booted. Then the cd will ask for where the ks.cfg file is and I have to type the location. I just want to pop the CD in and type in linux_clean or something and have it perform a custom install based on the information and specification in my ks.cfg. How can I go about doing this?

I'm running CentOS 5.4 with kvm and 1 Ubuntu 9.10 guest. I haven't gotten any sound from the start. I've done quite a bit of research and troubleshooting but have taken this as far as I can at this point. To start there was no virtual sound card, but after enough digging I found the option in virt-manager that creates that, created a new guest with sound and copied the line from the xml config file to my existing guest. The line I added in virsh was <sound model='ac97'/> And the virtual sound card now shows up properly in the guest, but still no sound in the guest. Sound works fine in the host so no hardware issues.
Next I followed the instructions here: [URL].. making sure to check the volume controls and user permissions, still no sound. I read somewhere on the net that SElinux messes up the sound, so I disabled SElinux on the host for testing purposes, but no joy. I also tried using modprobe snd-pcm-oss on my host but that didn't return any output so I'm not sure if that did anything. In short I've been shooting the dark trying different things and if anyone has an idea I haven't tried yet, I'd like to hear it.
I also found this on the net: [URL]... But this seems to refer to slackware and I have no idea which config file they are even talking about. I don't think it applies to me but who knows?
Could anyone point me to any centos usb installers (or how to create one). I've got a box with no optical drive. It can install from usb though.
View 4 Replies View Related1) Installed Cent os 5.4 in my system (name it as "guest os").
2) Downloaded the full kernel source, and patched the vanilla kernel to export symbol table (2 line change) [URL] (Yes I know that kernel should not be touched, if touched you should not seek help here . but I felt I didnt do any big change in kernel there). Besides we unset the config_smp & config_preempt parameter to make the kernel as not SMP and not preemptive .
3) Then compiled and booted with the new kernel 2.6.18, everything went fine . Now my gust os box is loading fine and I dont have any issue .
So now I need to install this above machine as guest OS in one more XEN machine cent os 5.4 (name it as "xen os").
So we created the image out of the above box "guest os" and added it as VM in xen os . But while booting it always hangs under some error like "/usb device sort of thing" (I dont have the screen where it hangs, but I do have the equivalent xen log from XEN OS linked to [URL] .
1) what the error is, and what need to be changed in my guest os build .
2) In general I am new to this VM and XEN installation, to be frank I am completely zero . Does changing the native os 5.4 to guest os need any change in kernel or something.
3) Does this case possible, install plain cent os in xen machine. After then patch the kernel in VM and boot with that . I guess it should not be possible ...
4) If possible guide me to some documentation where I can learn few basics over this.

View 3 Replies View RelatedI am having a problem running CentOS 5.4 in VMware which have appeared with the following error.
View 4 Replies View RelatedOn my bare metal server, I get about 130MB/s read from a software RAID 10 array, but when reading the same file from a VM via NFS over the VirtIO interface,I only get about 40MB/s.
Furthermore, the process for the VM uses >180% CPU on the host, and ~40%, and the 5 min average is ~1.5 on the host and guest. I have dual E5620's so I'm disappointed that the transfer is so slow, as I was expecting at least 90MB/s.
I'm new to being a sysadmin, so if anyone has some tips I can use to increase the transfer rate, and possibility reduce the CPU load as well I'd appreciate it. I'm assuming that 130MB/s is the max speed of two 7.2k HDDs, but if there's any way I can squeeze any more out that would be great too.
System specs:
2x Intel Xeon E5620s @ 2.40Ghz
8GB of RAM @ 1066Mhz

I've found a workaround, but the workaround doesn't make any sense to me.I suspect I am running into a bug of some sort.I've tried to search for a solution, but the search terms are too broad and I can't seem to find anything useful.I have a CentOS 5.5 system that I've set up Virtualization on (presumably Xen, right?). I have a RHEL 5.4 Guest OS using "Full Virtualization" method.When I was installing the RHEL guest, the entire server rebooted just as the RHEL guest was booting for the first time.Thinking that odd, but coincidental, I just let the Host server reboot and then started up the RHEL Guest again.The reboot happened again and in the same spot! When I say the server rebooted, I mean black screen...pause...bios screen.I finally managed to get the RHEL Guest booted by removing the DVD that I had in the DVD drive and disconnecting it from the Guest OS in VMM. Very, very odd. I can reproduce this behavior by simply booting a Guest OS with a DVD in the drive (so far I've tried only RHEL guests).
The reboot happens at the same place in the Guest boot process. It's when RHEL starts the UDEV script. Actually, a few seconds after the RHEL system displays "Starting udev" message. I've looked in both the CentOS and RHEL messages log and found nothing.It's not a huge deal at this moment, but I will be sending these servers out into the field and I can't control what the end users of these systems put in the DVD drives.
