Convert HVM to PV
Hi Everyone,
To convert an HVM install to PV, is it just as simple as creating a new config file, and use the "kernel" and "initrd" parameters to boot from a XEN kernel stored in the Dom0, and use the (ex) HVM''s disk image in the "disk" parameter?
Or is there something else I am missing?
Thanks

Bug#395114: xen-hypervisor-3.0.3-1-i386: dom0 crashes when trying to boot hvm domain while paravirtualized domain is running
Package: xen-hypervisor-3.0.3-1-i386
Version: 3.0.3-0-1
Severity: normal
-----BEGIN PGP SIGNED MESSAGE-----

Hi,
When you have a HVM domain running, if you try to boot a regular
paravirtualized domain, dom0 (or maybe the hypervisor) crashes immediately (reboot). The opposite
(trying to boot a HVM domain while a regular paravirtualized domain is
running) crashes the system as well.

paravirtualized vs HVM disk interference (85% vs 15%)
Hi,
We have found that exist a huge degradation in performance when doing I/O to a disk images contained in single files from a paravirtualized domain and from an HVM at the same time.
The problem was found in a Xen box with Fedora 8 x86_64 binaries installed (Xen 3.1.0 + dom0 Linux 2.6.21). The test hardware was a rack mounted server with two 2.66 Ghz Xeon X5355 (4 cores each one, 128 Kb L1

DVD writer problem
I have an NEC DVD-RW ND2500A (that's not the label I bought it under,
but that's what it really is.) It's supposed to read/write CDs, DVDs,
DVD+Rs, and DVD-Rs. I'm basically dual booting between XP and CentOS 4.
Following the recipe in "The Linux Cookbook", I tried to copy a DVD using:
dd if=/dev/hdd of=/tmp/diskfile.iso
then

mkswap, lvm and bootbits sectors
Hello,
I am confused by a warning from mkswap :
When making a swap on a LVM volume, I see the following warning :
mkswap: /dev/vg_SDB1/swap_test6_64: warning: don't erase bootbits
sectors on whole disk. Use -f to force.
Setting up swapspace version 1, size = 1048572 KiB
Is it safe to use mkswap -f in this case ?
(If that matters, the swap is intended for a virtual machine, and

About doing backups with kvm guests
Hi all,
I have two centos 5.4 servers that I use to run several windows kvm guests (10).
All works ok (more or less) but I have a problem with backups.
These windows guests are configured to use lvm partitions as a virtual disks. My
problem is when I need to do guests backups.
which is the best form to backup and restore these windows guests? Some examples?
I see snapshot's lvm

Mounting swap fails in domU (badiane)
Has anyone experienced a swap failing to be mounted in domU''s?
I created a LVM swap space, ran mkswap and made it available on the same
line as the root partition (also on LVM) in each of the domU''s config file.
But it fails to be mounted and I''m running without swap space. That
wouldn''t be too much of a problem if I had a lot of mem to play with but

syconf(_SC_PAGESIZE) versus getpagesize()
hello karel,
thanks a lot for the klibc portability merges.
current HEAD klibc failure:
mkswap.c: In function ?init_signature_page?:
mkswap.c:148: error: ?_SC_PAGESIZE? undeclared (first use in this function)
although POSIX encourages sysconf() could util-linux use getpagesize() ?

[PATCH] resize: handle empty UUIDs for swap partitions (RHBZ#1482737)
Avoid passing an empty UUID string to mkswap, which mkswap does not
accept (correctly) as new UUID.
In addition, print a warning when the UUID of a swap partition changed,
since it may require manual fixups in the guest.

mkswap - unable to relabel, operation not supported

swap labeling annoyance
I just upgraded a blade server via rsync from another server. Rebuilt the
initrd. It boots fine... except that it won't turn on the swap partition.
Several times, I've made sure swap was off, then mkswap -L SWAP-sda3
/dev/sda3, but when I do swapon -L SWAP-sda3, it complains it can't find
the device for the label.
The only thing I find while googling, other than redoing what I've

why i can not put my swap files in /dev?
I tried to create some swap files in /dev directory for my desktop.
the dd and mkswap were ok. but when I try to swapon it, i get this:
# swapon /dev/myswap
swapon: /dev/myswap: Invalid argument
but when I mv the file to some other directory like /mnt or /, the
swapon works.
could sb. tell me why?

Advantages of HVM vs. paravirtualization in a Linux-only enviroment?
Newbie here. My hardware supports HVM (full virtualization), but I only need
to run Linux on it. I initially tried to create a HVM domU, but couldn''t
get pciback to work with a telephony card I need for use with Asterisk.
However everything seems to be working fine under a paravirtualized guest as
long as I use permissive mode on the card. (Knock on wood-I''ve had some

Changing size of a xen guest filesystem
It should be easy, but I have not yet found a solution. Only some
methods involving use of dd, but that sounds a little scary to me on a
production server.
I wish there would be a command "virt-resize", but no... Maybe
"virt-clone", with the option --file=DISKFILE, could be bended to do this?
