Re: [CentOS-virt] get xen name from guest

Hi, how do you create the XEN-Config-File for your DomUs? As with DHCP you could use the MAC-Address to identify your DomU, too. Apart from that you may set the hostname during setup of the DomU. I am using templates to generate new DomUs: After copying the template with rsync into the LV for

Re: [CentOS-virt] moving from Xen to KVM

Hi, just two questions: 1. Is there anything faster than XEN-paravirtualization? 2. Why XEN 5? XEN 3 is quite stable, too. I have 31 DomUs up and running on a single Box - and have a strong feeling that even 60 will run flawless. But: All of them are Para-Virtualized. I have no problem with

Hi, where does you root-device reside on? Do you use sda or hda? Can you post your DomU-config (without comments) here? What messages do you get before LVM complains? It might be that you don't have the rigth drivers in your DomU-initrd (any more)... Kind regards, Nils -Original

Re: [CentOS-virt] High CPU usage when running a CentOS guestinVirtualBox

Hi Akemi, KVM uses a para-virtualized approach? With para-virtualized guests or with 32-bit guests running a single CPU there is no need to simulate the IO-APIC. Kind regards Nils -Original Message- From: centos-virt-boun...@centos.org [mailto:centos-virt-boun...@centos.org] On

Re: [CentOS-virt] Migrate windows VM from i386 Host to x86_64 host

Hi, sounds strange. Basically a dd should be enough to clone the machine. I guess the hardware-model that gets through to the Windows-VM changes when the Kernel-Achitecture changes. So basically you swapped a 32-bit mainboard with a 64-bit mainboard - as far as VM is concerned. So I guess you
