git://git.zytor.com/users/genec/syslinux.git Branch core-diskstart-boot-for-hpa. I found that INT 13h AH 08h in BOCHS used ES, DI, at least when using a partitionless HDD, causing "Boot error" from the magic check as it was loaded to the wrong location. HPA suggested wrapping INT 13h with the push/pop for ES's safety. This then lead to checking over for all int 13h calls in

Hello, xen-utils-4.1's pygrub is unable to boot VMs from a partitionless blockdev that has grub installed in first sector. I'm not sure it deserves a bug report, although it is kind of a regression from 4.0. Long story short: zeroing first sector of domU's boot blockdev fixes it. Maybe some of this report would be useful in the wiki, if someone else has the same (odd) setup. --- The

From: "Richard W.M. Jones" <rjones@redhat.com> If you use virt-make-fs to create a partitionless FAT-formatted disk image then currently you will get an error: $ virt-make-fs --type=fat . /tmp/test.img 'mkfs' (create filesystem) operation failed. Instead of 'fat', try 'vfat' (long filenames) or 'msdos' (short filenames). mkfs: fat: /dev/sda:

Hi, this is a forward from the debian bug tracking system, http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=595170: "syslinux for Windows provides the options -m (write an MBR) and -a (make partition active). These options make it easy to provide instructions for Windows users to make a bootable USB drive: just run "syslinux -m -a" on the drive, then drop some files on the drive

All, wondering if you can help, I had a perfectly working Mandrake 9.2 box running on a via Mini ITX 5000/classic. Asterisk (zaptel and libpri) was built from CVS head around 22nd July 2005. I decided now was a good time to ghost it up....although humorous for you all suffice to say, I ended up with a partitionless box! Following the install script I had created I built an identical server to

Hi, I''m running Xen on a Debian Xeon E3110 using the Debian 2.6.26-2-xen kernel. As filesystem for my lvm domU partitions I choosed xfs. I get the following error in kern.log of domU when booting a domU: blkfront: sda2: write barrier op failed blkfront: sda2: barriers disabled end_request: I/O error, dev sda2, sector 0 end_request: I/O error, dev sda2, sector 0 Filesystem

Hello All! I have a lot of virtual machines with KVM hypervizor. For VM's disks I use LVM Volumes. It's more suitable to install virtual machines direct to the LV-volumes without making partition tables inside the LV. In this case it is very simple to perform online-resizing and mount snapshots in host system to perform backups. So, my question is: Is it possible to install CentOS

I''ve been using lvm under centos to create the backing store for domUs and although the performance seems acceptable it has some shortcomings. The biggest of which is the LVM bug which prevents me from removing an lv (it says it is still mounted and it definitely isnt). I thought this was just a centos bug but it appears to be evident in debian and ubuntu too and I really can''t

I recently upgraded storage on our (first) xen server and would like to migrate the file-based vms I have in play to lvm-based storage... Can anyone point me in the right direction? Is there a way to mount a vm image file like I would using a iso image and a loopback device? Each vm''s disk file contains a partition table with root and swap partitions... In retrospect I wish I''d

Hello, i have a bit more complex login script. This script add common-shares, user shares, set some settings on firefox profile and so on.

Everyone, Is there a way to manually assign usb drives to a specified device label. Is there a way to force two usb drives to be labeled as /dev/sdc and /dev/sdd? I decided to build an archive server for the purpose of backing up other fedora/centos desktops at the office. I built a machine and have installed Centos 7.3 on it with all updates current. I also purchased a 3.0 usb sata drive

Hi, I''m trying to clarify if it''s at all possible to live resize a disk image. After trying and failing it seems that the reason a disk image cannot be resized - is that domU is only able to detect changes in partitions (eg. partprobe), not in block devices as the xvd driver lacks a rescan feature. My domU sees disk images as blockdevices - that is without a partition table,

Hi Everyone, I am going to get a storage server which will be connected to my Xen hosts via iSCSI/Ethernet. I wish to use LVM for the DomU disks. The storage server will have a RAID10 array, and 2 Xen hosts will connect to this (Each will have a 50% share of the RAID10 array, space wise). What is the best way to go about this? Should I: a) Split the RAID10 array into 2 partition on the

Hi, I was wondering, why/when it is useful or when should I avoid to use LVM. I think the big advantage of LVMing is if you modify (rezising, ...) disk and filesystem layouts "a lot". Are there any real pros or cons for following situations regarding e.g. management and speed? e.g.: I do have a server system raid for which the disk layout will not change; e.g. /var /usr /home will

I have a centos 5.6 server that has xen domUs installed on their on logical volumes. These logical volumes contain their own volume groups and again their own logical volumes.
