Reserved Memory release
I had temporarily started a VM, and it has allocated the memory for it. I have realised that after turning it down, the memory allocated to it, has remained reserved. Now, I need it for Dom0. So, how do I release the RAM that is reserved for VM, and make it available to Dom0? Is reboot the only option? _______________________________________________ Xen-users mailing list

Query - Issue creating VMs when not using bridge that Xen created, but using ovswitch.
*Hello,* I have installed Xen as Hypervisor with OpenSUSE running in Dom0. I want to use ovswitch (ovs) instead of the bridges that Xen created. In order to do so, I installed ovs in dom0 just like for the plain Linux. Xen has replaced eth0 with peth0, and has created a bridge named eth0. And eth0 is connected peth0 interface , vif2.0 interface (VM), and everything is working fine. Now I delete

Wrong size on a domU partition
Hi. I need more space on my domU server, so i create a file image to attach it to the domU. But when i load that image in the domU, show a size very different to the create. I create the file with this command dd if=/dev/zero of=/xen/domains/SRV03/opt-disk.img bs=1024k seek=30720 count=30720 (The idea is create an image disk with 30GB, but when i check the disk on the domU show 64GB.)

Where does PyGrub run?
Hello, I am still confused: does pyGrub run in dom0 as root? as it says in here: "PyGRUB used to act as a “PV bootloader”: it runs in dom0 as root, opens the PV disk image, reads its GRUB menu.lst, presents a GRUB-like menu to let the user choose a kernel which it copies to the dom0 filesystem, it then closes the disk image and eventually tells the domain builder to use that copy.

weird fail with conversion to bridges?
I''m converting my network from a "one interface per segment" to a "single connection with vlans", well, some hardware I have requires using different vlan IDs. suffice it to say I need bridges to connect a few different vlans that should all be one but can''t be because of firmware constraints. so my first step is to get shorewall to know about bridges.
