CentOS 5 Server :: Update Kernel In Xen Virtual Machine
Jun 20, 2010I installed the Centos 5.5 with XEN and put 03 virtual machines (Centos 5.5 too). I did this correctly, but I have a problem. In the virtual machine, I need update the kernel. I used "yum update kernel" and this is downloaded correctly and the menu.lst file is updated too, but the kernel not ran. I ran "grub-install /dev/sda" or "grub-install /dev/xvda" and received a error return. I read the device.map file and i ran "grub-install /dev/sde" and received a error return too.
The errors:
[root@vm01 ~]# grub-install /dev/sda
/dev/sda: Not found or not a block device.
[root@vm01 ~]# grub-install /dev/sde
/dev/sda1 does not have any corresponding BIOS drive.

CentOS 5 :: Create Virtual Machine From Existing Image?
Jan 3, 2011I had set up 4 virtual machines on centos 5.5 system where I directed the image locations to an external storage. I have lost the image files in the storage, but I have the image files that were copied from the virtual machine image location. I want to put up the same system on the same computer by copying these backup images. However, when I copy the image file to the same exact location and start the corresponding virtual machine I get "no bootable disk" error. When I increase the size of the image using "qemu-img" commands, I can get rid of this error, but get "error reading disk" error. Is there a way to overcome these problems, or is it not possible to restore a virtual machine by copying the machine image file under ..../xen/images?

Fedora :: Installed CentOS 5 In Virtualbox But Can't Ping The Virtual Machine?
Mar 10, 2009Running Fedora 10, I installed CentOS 5 in Virtualbox, but I can't ping the Virtual Machine...
From within CentOS, I can ping my laptop [known as the host?] but from the laptop I can't ping the CentOS Virtual Machine. I tried turning off the firewall on both too... CentOS was able to access the internet through my laptop right away without any configurations too.
Unless someone has an idea to resolve the above, I am also wondering about something else VirtualBox-related:
To see if it was possible to get around the above issue, I was going to install another CentOS virtual machine to see if I can get them to communicate both ways [if at all], but to do so, I think I have to install CentOS AGAIN on another allocated amount of hard disk space. This will take some time, so I was wondering if anyone knew if it was possible to just create a quick duplicate of the previous installation, if you wanted 2 different virtual installations of the same OS.
CentOS 5 :: VMware Server 1 Error When Powering On Virtual Machine?

View 1 Replies View RelatedCentOS 5 Server :: Create Qcow2 Image In 5.5 Virtual Machine Manager?
May 18, 2010I'm trying to set up a virtual machine environment in Centos5.5. My hardware fully supports virtualization, and I'm running qemu as the hypervisor with Virtual Machine Manager as the GUI to manage and create VMs. Host hardware is a Dell PowerEdge T710, with a quad core Xenon processor and four 1TB disks in a raid 6 array.
Within the Virtual Machine Manager when trying to create a new VM, there is the option to not "allocate entire virtual disk now". What format is created when you "allocate entire virtual disk now" and when you don't?
I want to create a qcow2 image format, but it doesn't look like it is supported. Does anybody know how to create a VM with a qcow2 image format?
When you create a blank disk with "qemu-img create -f qcow2 disk.qcow2 3700G", it indeed does create a qcow2 image. However, Virtual Machine Manager is unable to read these images, claiming that it is 15 megs or so in size (which is what it actually occupies in host disk space until you try and put a VM into it).

Oct 31, 2009I have two machines, one has XP service pack2, second one has CentOS 5.3 (Linux), they are connected through crossover cable. I have configured everything fine but don't know why till now can't ping!
A. Windows machine settings as follows:
IP Address: 192.168.1.3
Subnet Mask: 255.255.255.0
Default Gatway: 192.168.1.1
+ Firewall is turned OFF.
B. For Linux machine, I will list everything stored in network files, logged as [root@localhost ~]# :
1. /etc/sysconfig/network:
ifconfig eth0 192.168.1.4 netmask 255.255.255.0 up
route add -net 192.168.1.0 netmask 255.255.255.0 eth0
route add default gw 192.168.1.1 eth0
NETWORKING = yes
NETWORKING_IPV6=no
HOSTNAME=localhost.localdomain
2. /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE="eth0"
IPADDR="192.168.1.4"
NETMASK="255.255.255.0"
ONBOOT="yes"
BOOTPROTO="yes"
3. /etc/resolv.conf
nameserver 192.168.1.4
search locadomain
4. I restarted network service using this command:
/etc/init.d/network start
everything is fine. When checking using ifconfig command. I get the following:
eth0 Link encap: Ethernet HWaddr 00:08:0D:EE:19:66
inet addr:192.168.1.4 Bcast:192.168.1.255 Mask:255.255.255.0
inet6 addr:........
[code]....
I mean I assigned the IP: 192.168.1.4 to Linux machine (Eth0). I did everything above and can't ping till now, when pinging from windows or Linux I get a message "destination host unreachable" restarted Linux many times but same result. NETWORK CABLE is working fine I tested it.

View 2 Replies View RelatedFedora :: Virtual Machine Manager
Jul 30, 2009I'm having some issues with a windows virtual machine. The system is Fedora 11 and the virtual machine is Windows 2008 Server. If I start the virtual machine from the virtual machine manager, it only has a single cpu despite my setting it to eight. If I start the machine from the command line, I can get four cpus but not eight. In both cases windows seem to display the eight cpus in the device manager (or whatever program it is). It has been suggest that windows was imaged on a four core machine before being loaded on the eight core machine and that something in windows is maxing at four cores. But that doesn't explain why the virtual machine manager can only start one cpu. I just played around on my home machine with a fedora 10 live cd and it recognized the two cores on that machine and used them from the virtual machine manager without problem. Also upped it to three cpus without problem.

OpenSUSE :: Cannot Create A New Virtual Machine In Xen
Jan 5, 2010I have been unable to create any type of Windows VM in Xen. Every time it tells me that the processor(s) in the machine do not support full virtualization. After some research, I found several articles regarding the vmx setting in /proc/cpuinfo not showing up when the xen kernel is booted versus it showing up in the default kernel. Of course, I am not seeing the vmx extension in /proc/cpuinfo after I boot to the xen kernel. In the other posts where other people are in the same situation, the only resolution is to upgrade to the 2.6.16 xen kernel. I am already past that:
linux-vxke:~ # uname -r
2.6.31.8-0.1-xen
yet I am still unable to create any form of Windows VM. I have even seen that some people are able to create a partially virtualized Windows VM, and they report that the message is only a warning. However, I am unable to get past this message. I am running a Dell Optiplex 760 with an Intel Core 2 Duo E7300, and I have the VT-x setting enabled in the BIOS. Has anyone else seen this situation or have any thoughts on why this is happening?
