Hi! as far as I understood from "xml format for openvz driver" thread available at [1] it should be possible to specify via libvirt disk size and disk inodes for openvz VM.But the following device section in VM xml description doesn't set disksize and diskinodes properly (it looks like those parameters are taken from default OpenVZ config and not as they are specified in libvirt tags): <devices> <filesystem type='template'> <source name='centos-5-x86'/> <target dir='/'/>...

When I open "My Computer" window on a client, the drives are marked by a red cross, as if they were disconnected, and the disksize is zero. I can decend into the folders on the drives, and here all the files are there as expected. After opening the "My Computer" window, a panic error message is logged in log.smbd. The error message is added below. As long as I'm in a Samba share, the error message is reapeated...

...usefull for removable media like diskettes, Zipdisks, USB Flash keys, etc.. I don't know if the fact that Syslinux is now installed using blockmapping is really breaking the usefullness for harddisks. You already mentioned system attribute will protect from defragmentation tools, but how about disksizes? Isolinux and PXElinux will remain unreplaceable, so it would be most interesting to see most development in every component that is not Syslinux itself. PXElinux, Isolinux, Memdisk, Menu, Sample programs. Since 3.10preX, Memdisk's INITRD can take multiple files. However, can it also take a...

Hi Jens, this series removes the revalidate_disk() function, which has been a really odd duck in the last years. The prime reason why most people use it is because it propagates a size change from the gendisk to the block_device structure. But it also calls into the rather ill defined ->revalidate_disk method which is rather useless for the callers. So this adds a new helper to just

When I say busybox it''s actually VMware ESX server which seems to use busybox (which I guess is the case a number of other software appliances) . Reason for wanting to install puppet is to run the cli tools to create nightly vmware snapshots. I''m happy to give it a go (and add the docs to the wiki) but I''m not too sure at this stage how big a task this might be and what,

Recently, I got many reports about perfermance degradation in embedded system(Android mobile phone, webOS TV and so on) and failed to fork easily. The problem was fragmentation caused by zram and GPU driver pages. Their pages cannot be migrated so compaction cannot work well, either so reclaimer ends up shrinking all of working set pages. It made system very slow and even to fail to fork easily.
