| <pre>
| |
| I am planning on running several virtual machines on a single host. I
| |
| will have two or three Linux baeed virtual machines and one or two
| |
| Windoze. I plan on using a F11 host system.
| |
| | |
| I need most of these to run automatically on boot-up of the host
| |
| system. It would be really nice if I could use something like the
| |
| Ctl-Alt-FN to be able to access and switch between virtual machines.
| |
| This needs to be stable. The machines that these virtual machines are
| |
| intended to replace are often running hundreds of days between
| |
| reboots.
| |
| | |
| My gut feel is that the virt-manager suite might be the way to go,
| |
| editting the apropriate xml files as required. I also see there
| |
| is a qemu launcher and it seems to work okay. I suspect there are
| |
| others as well.
| |
| | |
| What tends to be the consensus here on the various virtual machine
| |
| managers? Are there white papers somewhere that could give some
| |
| insight?

| | "The KVM based virtualization in RHEL-5.4 is not nearly so far behind |
| For stability and long-term maintainability, I wonder if you've
| | Fedora as you might think. The {{package|libvirt}} mgmt stack in RHEL-5.4 was |
| considered using RHEL or CentOS? That means you have to use Xen as
| | rebased to be near parity with [[Releases/11|Fedora 11]], and KVM in RHEL-5.4 is |
| the hypervisor, but if you use libvirt / virsh / virt-manager, the
| | also pretty close to that using what's best described as a hybrid of |
| future upgrade path to KVM is reasonable. All tools stay the same,
| | kvm-83 and kvm-84." |
| and you just need to run our forthcoming v2v tool on the guests (or
| |
| reinstall the guests) when you upgrade.

| |
| The only one we're supporting here on | |
| Fedora<ref>http://fedoraproject.org/wiki/Virtualization</ref> is libvirt / virsh /
| |
| virt-manager. Use 'virsh edit <domain>' to edit the XML for a domain.
| |
| The same commands will work on RHEL / CentOS too.

| a bug ({{bz|508865}}
| |
| <pre>
| |
| I suspect this is the result of trying to use SELinux to protect everything
| |
| and the mandatory access control idea that everything is disallowed except
| |
| that which is explicitly permitted.
| |
| | |
| But, I just do not understand what and why CD/DVD images and devices are being
| |
| protected. Furthermore, when virtualization changes a file's context
| |
| (including /dev/sr0), could this effect other valid usage of these
| |
| files/devices? If there is no effect for other applications, then just what is
| |
| protected?

| ==== Forward-ported Xen dom0 Kernel Patches ====
| |
| Previous dom0 support in Fedora was based on patches against 2.6.18 which were carried
| |
| forward to the kernel version found in the Fedora release of the time. As of
| |
| Fedora 9 <ref>http://docs.fedoraproject.org/release-notes/f9/en_US/sn-Virtualization.html</ref>
| |
| this practice ceased and work began on creating a pv_ops-based kernel<ref>http://fedoraproject.org/wiki/Features/XenPvopsDom0</ref> cabable
| |
| of functioning as a dom0, and based on the most recent kernel.
| |
| | |
| This work is incomplete and not expected to be until F12 or F13, but
| |
| there have been experimental kernels built (add link to previous dom0 news).

| |
| <pre>
| |
| For reference here are the latest Xenlinux 2.6.18 forward-ported patches to
| |
| standard/kernel.org Linux 2.6.29 and 2.6.30. Forward-porting has been
| |
| done by Novell for OpenSUSE. Novell also has a forward-port to 2.6.27 for SLES11.
| |
| | |
| See this thread for the latest patches:
| |
| http://www.nabble.com/2.6.30-dom0-Xen-patches-td24293721.html
| |
| | |
| Patches for 2.6.29 and 2.6.30 available here:
| |
| http://code.google.com/p/gentoo-xen-kernel/downloads/list
| |
| | |
| Also available here:
| |
| http://x17.eu/xen/
| |
| | |
| Someone interested in building Xen dom0 capable kernel for F11, based on
| |
| these patches? These patches are still more stable and mature than the
| |
| pv_ops dom0 code.. Also, these patches have the full Xen feature set
| |
| (pv_ops still lacks some features).
| |
| | |
| If you have any problems with these patches, please post to xen-devel mailinglist.
