similar to: where is the xend code that is used to communicate with blkfront and blkback?

I was playing with suspending and resuming Xen domains. Suspend and restore seems to work. However, when I reconnected with ''xm console'', I got the following error message on screen. Should I be concerned? [root@ROUGE xen]# xm console FedoraCore2 ************ REMOTE CONSOLE: CTRL-] TO QUIT ******** xen_blk: Unexpected blkif status disconnected in state connected blkfront:

Hello, I trying to run XEN 2.0 (2.4.27, 2.4.28, 2.6.9) on gentoo 2004.3. When i boot guest domain i get this: anubis xen # xm create -f ttylinux -c Using config file "ttylinux".

I would have sworn that someone on the list had a way to Xenify a stock RH kernel but I was not able to dig it up on the archives. If this does not exist I am sure it would be a nice addition to Xen to be able to patch and build some kernels that are compatable with some of the popular distributions. -- Alvin Starr || voice: (416)585-9971 Interlink Connectivity ||

hello, I wonder where the Xen''s name came from? I looked at the Xen FAQ, and there is no information. That should be there, right ;-) Merry Christmas to everyone on the list ;-) AQ ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

On my lex mainboard with a Via C3 cpu, xen 2.0(.1) reboots (nearly) immediately without any outputs. The same setup/version boots without problems on a via epia M board with a Via C3-2 cpu (Nehemia), having a rather different chipset. Starting with option noreboot, nobiostables doesn''t change anything visible. Is this a known problem? Or just a knowingly unsupported chipset? Have you

I am trying to create an additional domain and have created a configuration file based on the examples. When I try to boot the domain, it eventually hits a Kernel panic, as follows: Red Hat nash version 4.1.18 starting Mounted /proc filesystem Mounting sysfs Creating /dev Starting udev Creating root device Mounting root filesystem mount: error 6 mounting ext3 mount: error 2 mounting none

Dear list, I''m trying to get Xen working on a P3-600E with 320 MB RAM. (256+64) It has suse linux 9.1 installed on it, and I tried to get xen running with both the binary download from the xen pages and the suse xen packages mentioned on this list some days ago. Both ''install packages/kernels'' lead to the same error: (XEN) Not enough memory for DOM0 memory

Hi, I''m getting the following oops on startup, and I''m not quite sure why. It looks nasty though, with an invalid page being mapped into a process, and a strange looking EIP ... do_wp_page: bogus page at address 00000449 VM: killing process kmodule Unable to handle kernel NULL pointer dereference at virtual address 00000449 printing eip: 00001eca *pde = ma 0d183067 pa

I am a bit puzzled on how the block device mapping works for Xen guests. Or particularily the fact on how the device shows on the guest side. When configuring the domain, one can specify the device name the partition should appear with inside the guest. And if that device does not exist on the host side, xend complains. A workaround for this was to specify the device with explicit minor and major

Hi, When a domain shuts down it seems to stay visible in the output of xm list (see below) even if I do an ''xm destroy''. Has something changed (they used to disappear just fine for me)? I am running Xen 2.0 (fairly up-to-date). Name Id Mem(MB) CPU State Time(s) Console Domain-0 0 395 0 r---- 2377.2 cagnode91-clone 10 199 2

Hi, I am trying to replace uml with xen, but I cant get the unpreviliged Domains booting.. Ive tested a cuple of filesystems in a file (ext3 or xfs formatted) and Ive also tried the ttylinux-xen image. But I always get this error: VFS: Cannot open root device "hda1" or unknown-block(3,1) Please append a correct "root=" boot option Kernel panic - not syncing: VFS: Unable to

Hi people I am new to Xen and having some trouble getting it up and running. I am trying to install it on a Dell Poweredge SC420 that has CentOS (RHEL3 clone) installed. The error that I am getting when I first try to boot into the Xen kernel, after having installed the binary and adding the necessary lines to grub.conf is : ---snip--- md: Autodetecting RAID arrays md: autorun ... md: ...

Hi, Some questions here : 1. Is there a way to compile kernel 2.6.10 or 2.6.9-mm1 with xen 2.0? I tried both (with mkbuildtree from linux-2.6.9-xen-sparse), and both failed (on different places). My primary goal is to use reiser4 on both xen-0 and xen-U kernel, so I''m more interested in -mm kernel. 2. If I use kernel 2.4.27 (xen-U), top doesn''t show correct cpu usage

Is there a way to discovery how much free memory I still have to use in a new domain? Another question is about cpu usage. I guess that xen scheduler allocate a fixed time slice for all virtual machines and does not make any idea if the virtual machine is using or not using all this time, right? How I can identify if CPU is the bottleneck? Thanks! -- Flávio Bruno Leitner

Hello, I can''t seem to get the network going. I found this message in the log of Domain0: ----------------------------------------------------------------------- Dec 1 15:39:18 zms wait_for_sysfs[4180]: either wait_for_sysfs (udev 039) needs an update to handle the device ''/class/net/br0'' properly (no device symlink) or the sysfs-support of your device''s

hello, I''m booting xen on iTuner over serial console. It seems to me that it is bug that unless I explictly specify "console=com1" I get unhelpfull message "Unknown Interrupt" and halt (infinite loop). sh-2.05b# /sbin/kexec -e Starting new kernel Unknown interrupt adding "console=com1" fixes this problem for me so I doubt it I''m going to look

Just did a quick scan for that error message in the kernel source. Turns out it''s triggered in net/bridge/br_fdb.c:289. if (!is_valid_ether_addr(addr)) return -EADDRNOTAVAIL; Interestingly enough, it''s claiming that the mac addy isn''t any good! 8-( I''ll go add a printk line to that to see if I can determine what kind of data

Hi, I have a question, If I start 2 or more guest linux, does the physical memory of code segment and readonly data segment be reused? What''s the relationship between the physical memory and the number of guest os that can create? xiaofeng ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT
