Let's assume that your own IP is 192.168.1.1, your gateway is 192.168.1.254 and your network is 192.168.1.0/24. You should make a bridged interface on your host machine, like this in /etc/network/interfaces file auto lo iface lo inet loopback auto br0 iface br0 inet static address 192.168.1.1 network 192.168.1.0 netmask 255.255.255.0 ...
KVM provides full hardware virtualization, but you can use paravirtualized disk and network drivers (virtio). Most current Linux distributions will use them by default provided you've configured them when setting up the VM. In full hardware virtualization, every component of the virtual PC appears to be a physical PC and the guest OS uses the same device ...
Windows will only run in HVM and PV-HVM modes (which use the modified version of QEmu and require VT/AMD-V) You're looking for PV mode if you require a non-VT/AND-V CPU, and it only works with modified Operating Systems: Xen PV guest kernels exist for Linux, NetBSD, FreeBSD, OpenSolaris and Novell Netware operating systems. From: Xen Overview QEmu ...
Xen runs on RHEL6 & CentOS6. RedHat does not support this, but Xen still strives to run on RHEL6. See http://wiki.xen.org/xenwiki/RHEL6Xen4Tutorial for a tutorial and a list of required RPMs. This tutorial says: As a default RHEL6 does NOT: RHEL6 does not ship Xen hypervisor or tools. RHEL6 does not ship Xen dom0 capable kernel. ...
KVM supports para-virtualization for certain drivers, but not for the entire Guest. They explicitly define themselves as a full virtualization solution for Linux.
Try installing CentOS 7 in fully-paravirtualized mode. You can use a kickstart to automate the installation; so long as the grub configuration files are patched to be readable by XenServer 6.2's pygrub, the virtual machine will boot. XenServer Tools will install properly inside the paravirtual machine. The next version is due soon, and you may have better ...
RHEV can support nesting however, for this to be configured, your "overlords" need to do the setup first. What you can do instead, if your VM has the resources, is use containers inside it. LXC and Docker come to mind, with Vagrant lagging behind (it requires vbox, which is still doable). If the app supports it, I'd even try and make do with a simple ...
After a lot of experimentation, I finally found the answer: Yes, pygrub needs an initrd/initramfs. So, I do it this way: Build the kernel the manual way make menuconfig && make && make modules_install Copy the resulting bzImage to /boot Create the initrd using genkernel --oldconfig ramdisk Feed the path to the kernel and the initrd to ...
I found the answer to this awhile back. pygrub expects the boot partition to be number 1. I had to renumber my partitions with parted.
If your target VM is a BSD system, pygrub can't read FFSv2. You'll need your root filesystem to be FFSv1 -- which is more easily said than done.
While creating VMs using virt-install or any virtualization product/tool , you need to specify the type of virtualiztion you want. Ex:- with virt-install -v ensures hvm machine and -p gives you a paravirtualized machine. With linux also one needs to enable VT support if present. Yes Yes. With VT enabled and type of VM chosen the virtualization type changes ...
menu.lst is not a initrd image. That is your problem here. The next problem is that your kernel is not a kernel but a xen-hypervisor. The hypervisor replaces the kernel on a Dom0. On a DomU you need a xen-kernel to run it in PV-mode.
It's not aconfiguration issue as such. Xen allow for virtual disks to be mapped to partition names. I used to do it that way in the past but revert to a more classic approach later on for several reasons. As far as i remember, you use the vdisks as partitions or even add partitions on top of it. You would end up with something like xvda1p1 iirc.
If you don't mind switching to KVM, oVirt is an out of the box VDI and SVI system. It is actually used for VDI at academic institutions
