...etup" the disks for the VM before xen/qemu tries to use the devices and allocate to the domu. I''m using xen 4.1.3 on Debian testing, and using the xm toolstack. In particular, I''m allocating a ram drive (/dev/ramX) to the domU, but I need to ensure the module is loaded, the ramdrive exists, and also use dd to copy the image of the drive into the ramdrive (partition, format, and files all in one go), all before the machine bootup commences. Thanks for any suggestions. Regards, Adam -- Adam Goryachev Website Managers www.websitemanagers.com.au

...ways to make it faster at a price of extra complexity (reusing the fixtures, doing a rollback in the end of the test, etc), but still - it is much slower than what I would like a unit test to be. Today I had a very simple idea (why, oh why didn''t I have it half a year ago?!). Set up a RAMDrive (a memory area treated by the OS as a virtual "disk") and put SQLite3 database on it. Voila!

Hi, I want to Boot up from a USB Disk-On-Key, Pull up a menu of: Start Fresh install of WBEL 3.0 Start Fresh install of WBEL 4.0 Start Fresh install of CentOS 3.6 Start Fresh install of CentOS 4.2 Load Win98 boot disk and end with command prompt. My problem is that I'm a novice user (sounds nicer than a newbie :)) ) and my experience with Linux was vanilla installs with no

...run to load images to/from the lan. I've got 6 different disk images setup and the all work great except for the ones for the 3Com 90x cards. IF i use the disk image in hte floppy, works great, no issues, if I feed that image thru pxelinns/memdisk, when the image begins to boot it creates a ramdrive which it uncompresses data into to startup the LAN, I get the old DOS "Abort Retry ignore" error when attempting to unzip the disk file onto the ramdrive. Hittign retry works and it unzips, but the network driver just hangs the machine at this point. The same disk image booting from...

Hi all, I want to have a warmboot nonvolatile ramdisk to put and start XP from ram. That means that the ramdisk and its content have to survive a reboot on a "normal computer"! (No battery ...hihi) First I make a try with Microsoft ramdrive.sys and switch /e in config.sys from Dos 6.22 and with qemm386.sys but that doesnt work for me. Qemm (8, 97)does not work together with harddrive (only floppy) and syslinux. Microsoft's ramdrive DOESNT SURVIVE a reboot (for me). This is very angry, because now I cant use ramdrive.sys for XP(...

...l-Core Opteron for SIP routing and SIP 2 SIP calls (no recording) One Serial Over Ethernet Storage for recording the calls (the two asterisk servers will commit to that device) For the setup I was going to put a lot of RAM on the serves something like 8GB and make asterisk record the calls to a RAMDRIVE. Another process will run with low priority moving the Recordings from the RamDrive to the Storage. If Asterisk One dies, Asterisk two assumes. If SER dies, ASTERISK one or TWO will handle without the proxy. We need to avoid single point of failure as also be able to scale well. Other possibi...

...ke any compressed initrd.gz >32 meg work with pxelinux. I am using "atftpd" as the server, with --no-blksize specified to disable the blksize command. The symptons are anything ranging from a failure to uncompress the ram drive to file system consistency failures on the e2fs formated ramdrive. We're looking at the thought of net booting all of our servers and running the OS completely off the ram disk :-) However, to do that, for what we want, we need to bloat that initrd.gz to about 45 meg, if we're gonna go this route. Thanks for any pointers... -- -- Jason Fesler <...

...tributed that to the extremely slow disks we use to back it, so now that we're expanding I set up a new gluster cluster with state of the art NVMe SSD drives to boost performance. However, performance only hopped up to around 2.1MiB/s. Perplexed, I tried it first with a 3-node cluster using 2GB ramdrives, which got me up to 2.4MiB/s. My last resort was to use a single node running on ramdisk, just to 100% exclude any network shenanigans, but the write performance stayed at an absolutely abysmal 3MiB/s. Writing straight to (the same) ramdisk gives me "normal" ramdisk speed (I don't...

The BIOS on my laptop does not support booting from USB. I would like to be able to have my Windows XP on a partition on a USB disk drive and be able to run from the USB disk using perhaps a CD or floppy to bootstrap the system. My questions: 1). Is there a way to use syslinux and friends to do this? 2). If not, is there some other boot loader that may work? 3). Is there any hope at all?

Hello all, I've been following this project with interest, and have had great fun implementing Isolinux within the FreeDOS cdrom distribution. Since I'm not that an expert at Linux, I would like to know how I can *succesfully* generate a bootable image from a partition. Situation is like this: (640MB RAM on system) 60GB IDE harddisk, primary partition 1 win98 500MB extended partition

Hi list, Here is the idea. I am running a domU out of a partition on a USB drive. I use the other partition to store the domU state. Then I carry this USB key to my office and restore the VM at the point where I left it. Thus I am trying to use xen''s virtualization to carry my desktop on a USB key. I have put up a web page explaining the details and a script to prepare the USB key.

Hi all, Advance apologies if this is OT; if so, please mail me offlist. A client is considering using CentOS5.1 for an embedded project. They will be booting from Compact Flash. The CF in the device is being controlled by a VIA VT6421 SATA/RAID controller. Are there drivers available or must we truly 'roll our own' when compiling the 2.6x kernel for this? I've done some

Hello all - I'm getting a weird error message on a custom system I'm trying to setup using SAMBA. The box is running a slightly modified 2.0.37 linux kernel to run the entire OS out of a huge (128 MB) ramdrive. This particular box will be running for years before anything should fail in it. Anyhow everything works fine so far, except neither smbd or nmbd will start with the following error: unable to get hostname <whatever hostname I try>. I've even used localhost as the hostname, but neith...

Hi, I run a little router/firewall that also acts as a print server for the linux and win98 clients on the LAN. I have the harddisk configured so that if there is little activity, it spins down (hdparm -S 12 /dev/hda). I added smbd/nmbd today and with the two services running, the hard disk drive spins down but wakes up about every 12 minutes. Without the services, only a major event causes them

I read the following about memdisk : .... For any other size, the image is assumed to be a hard disk image, and should typically have an MBR and a partition table. The disk C/H/S geometry is determined by examining the partition table, so the entire image should be partitioned for proper operation. .... I'd like to create a bootable cd, wich boots a linux and some other tools. While
