virtual disk/block-device problem
I am trying to write a script to handle setup of domains using virtual block devices for their root FS and have been unable to get the virtual devices to work with any sort of consistency. This is using xen-1.1.bk on Redhat 7.3 (I had to rebuild all the tool binaries to run on 7.3). Anyway, I would first like to make sure I am using the vd/vbd stuff correctly. Here is an example of the problem I

PV DomU stopped responding, won't boot, stuck in paused state
Yesterday, I had a PV OpenSolaris DomU stop responding. I looked on my xen machine and it was in a paused state. I ended up destroying it and then doing xm create to bring it back up. It won''t boot, and I think PyGrub is hanging. Not sure how to resolve this, there aren''t any errors being presented in xen/xm itself. If I try ''xm create config.conf'' it just

[PATCH] Ensure blktap reports I/O errors back to guest
There are a number of flaws in the blktap userspace daemon when dealing with I/O errors. - The backends which use AIO check the io_events.res member to determine if an I/O error occurred. Which is good. But when calling the callback to signal completion of the I/O, they pass the io_events.res2 member Now this seems fine at first glance[1] "res is the usual result of an I/O

Hi. I'm testing a centos 5.4 xen PV guest on top of a centos 5.4 host. for some reason, the disk performance from the guest is awful. when I do an import , the io is fine for a while then climbs to 100% and stays there most of the time. at first I tougth it was because I was using file-backed disks, so deleted those and changed to LVM, but the situation did't improve.

Problem with Xen4CentOS

With the latest versions of all packages installed [1], we see failures in live-migration of stock-CentOS6 HVM guests, leaving a "Domain-unnamed" on the source host, while the migrated guest runs fine on the target host.

RFH: loopback & blktap(2) and CDROM
Hello, I''m currently trying to understand some problems I had in the past with mixing look-back with blktap(2) for HV and PV domains. I''m stuck reading the source code, so I''d like to get some help from the list. Interrupt me if I got something fundamentally wrong in my understanding so far: 1. With pure-HV the domU gets an emulated IDE (or whatever) disk. The

To start in the Dom 0 I created the LV''s with lvcreate -n guest_boot -L 100M
