VMware images
by Ted Miller 07 Jan '08

07 Jan '08

Can someone please clarify the status of minimal install images of Centos 5 for VMware? I see the work that 'tru' did, but it is still at 5 (not 5.1). Is that the best image available (just run yum update), or what about the minimal image listed on the VMware Virtual Appliance site? Ted Miller Indiana, USA

tick_divider kernel parameter for guest vm
by Fabian Arrotin 03 Jan '08

03 Jan '08

When upstream released 5.1, everybody wanted to test a new kernel parameter that could adjust the system clock rate at boot time to something else than the standard 1000Hz clock rate. A lot of testings has been done (thanks to Akemi Yagi for her great work) and you can see the results here : http://bugs.centos.org/view.php?id=2189 As you can read at the bottom of the comments, it seems it was a typo in the official RH Release Notes : you'd have to read divider= and *NOT* tick_divider= ! (see http://www.centos.org/docs/5/html/release-notes/as-x86/RELEASE-NOTES-U1-x86…) It seems so to work with the correct kernel parameter and so there is no need to build a kernel-vm for CentOS 5.1 guests .. (it's still needed for example for 4.x ..) Keep on reading the comments on bugs.centos.org for further informations ... I assume that upstream release notes will be corrected to reflect the real parameter -- Fabian Arrotin <fabian.arrotin(a)arrfab.net> Solution ? echo '16i[q]sa[ln0=aln100%Pln100/snlbx]sbA0D4D465452snlbxq' | dc

No CD/DVD option in virt-manager for para-virtualized VM?
by brad lodgen 02 Jan '08

02 Jan '08

Hey Everyone, I'm fairly new to linux(6 months or so experience) and very new to using Xen virtualization. First post on the mailing list here! Thanks in advance for any and all help attempts, whether it actually helps me or not! I've been reading the Red Hat virtualization guide and in the appendix labs, using virt-manager, it says to: "Specify either CD-ROM or DVD and enter the path to install media. Specify ISO Image location if you will install from an ISO image. Click Forward." Is this option only available in fully-virtualized VM installs? It asks for URL media only when picking para-virtualized VM. Brad

open-vm-tools for latest CentOS-4 and CentOS-5 kernel-vms
by Johnny Hughes 02 Jan '08

02 Jan '08

All, There are some (very much) testing open-vm-tools RPMS for both the CentOS-4 and CentOS-5 i386 and x86_64 kernel-vm's and standard UP kernels. The kernel-vm's are available here: http://people.centos.org/~tru/kernel-vm/ (The kernel-vm kernels are designed to run inside the VMs at a clock rate of 100HZ instead of 1000Hz.) The open-vm-tools are available here: http://people.centos.org/~hughesjr/open-vm-tools/ The purpose of these RPMS (open-vm-tools) is to replace the VMware-Tools RPMS that come with VMWare. Please remove VMWare-Tools inside the VM if you are going to install these open-vm-tools for testing. There is an xorg.conf file that should be used to replace the one in /etc/X11/ inside the VM Client only (not on your host). The open-vm-tools SHOULD ONLY be installed inside a VM Client and not on the VM Host. These open-vm-tools RPMS are only designed to work with CentOS VM Clients/Guests (should not matter what the host is), though they should also work if RHEL4 or RHEL5 are the VM Clients/Guests. Documentation for the vm tools can be found here: http://open-vm-tools.wiki.sourceforge.net/Packaging and chapter3 here: http://www.vmware.com/pdf/server_vm_manual.pdf (In that PDF file, the installation parts can be ignored, but the configuration parts and usage parts should work) Thanks, Johnny Hughes
