Domu from iso

The domU's are still running on the servers, and I now want to create config files for them, while they're running. How would I be able todo this? You can use "xm list -l" to dump the configuration in SXP format; then you should be able to use "xm new" or "xm create" with the "-F" option to load an SXP-based config file. See the "xm" man page for more info - that's where I dug up this.

One additional thing to note is that for 64bit HVM domUs you need to make sure that acpi, apic, and pae is set to 1 on domU config file. This dhclient bug can be triggered if you are running your dhcp server in your dom0. The issue is not Xen specific.

The bug is that dhclient is incorrectly trying to validate the UDP checksum and discarding the packets. There is a patch to dhclient which fixes this issue. If you are seeing this you are encouraged to report the bug to your Linux distro. Jump to: navigation , search. SUSE Suomi. About Us. Success Stories. Investor Relations. Social Impact.

XEN: How to CD-boot fully-virtualized DomU's after initial installation This document is provided subject to the disclaimer at the end of this document.

Booting to a CD after installing a fully virtualized DomU is straight forward and simple, more so than para-virtualized DomU's. Then, once installation is completed, we can convert the domain to boot via PyGrub so that it can benefit from the increased speed that comes with paravirtualization PV over full hardware virtualization HVM.

This article looks at installing CentOS 7 bit , but the process can be used for other OSes as well. Here, I am using Xen 4. Now complete the installation steps. Go through the localization portions as needed, important bits outlined below:. Make sure to set a root password while the installation is proceeding. Then, once the install is complete, choose the Reboot option.

This will probably cause the DomU to hang, but that's OK. Hop back over to Dom0 and kill it:. In order to for Xen to read the modified config you need to undefine the guest-1 DomU.

We just delete it. That works. Comments anonymous says:. August 12, at pm. Anonymous says:. September 26, at pm. October 14, at am. August 20, at am. October 1, at am. Leave a Reply Cancel reply Your email address will not be published.
