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

Hi folks, I''m trying to use the atropos scheduler with Xen. Couple of questions: - the scheduling param *has* to be specified at boot time right, or does Xen allow changing the scheduling scheme at run time?? - xm help atropos gives a very vague message at best, perhaps we could make it more elaborate: xm atropos DOM SLICE PERIOD LATENCY XTRATIME o is DOM the vm ID or the vm NAME (as

For iSCSI, have a look at iscsi-init at sourceforge. http://iscsi-init.sourceforge.net.

Hi, Currently TLS wraparound segments are a problem in Xen, since the kernel needs to be protected by keeping the user space segments out of kernel space. A few weeks ago Roland, Jakub and myself brainstormed about this problem. One of the things that came up is that the positive (glibc private data) and -ve (TLS) data are not generally used at the same time. This lead to one of us (I

I rebooted xenU from console (dom2) and exited (ctr-]). xm list does not report 2 anymore yet I can log into 2 via console and it is running just fine. Is this a bug? I''ll pull/rebuild and see what happens.. (this is xen-2.0, cset 1.1321.1.1, rh7.3 dom0/dom1) ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on

In case it helps anyone, here''s a script I use to boot xen0 over iscsi with an initrd using linux-iscsi and iscsi-init (both on sourceforge). Some (or most) of it might be debian (sarge) specific though. The script goes in /etc/mkinitrd/scripts and puts the bits and pieces in place. It has to prepend stuff to /script in the resultant initrd so it does a few funny things. Add your Ethernet

FWIW, I assign my MAC addresses as "FE:FD:XX:00:YY:ZZ" Where: XX = what xen does to MAC addresses (00 in xen0, 01 in xenU) YY = vmid (unique across all physical servers) ZZ = interface number in xenU (00 = eth0, 01 = eth1) Works for me! Someone asked about trying to find a duplicate MAC address on a network - it''s pretty hard to do as the whole idea is that MAC addresses are

Hi, Thanks to everyone involved in the Xen project. I think it is great and can''t wait to get my hands dirty with it. In the meantime, I cannot boot Dom0 on an ibm x335 and I am not sure what the problem is. Any insights are welcome. Here is what my grub.conf file looks like: title Fedora Core (2.6.8-1.521) root (hd0,0) kernel /vmlinuz-2.6.8-1.521 ro root=/dev/sda9

Just to error test my own thinking here, there seems to be the following options for remote graphical access to a running domian vm. Besides the normal network service via a port and a raw console, the options are straight X, VNC, and XN. X - supports a single X window running on a local XServer, tied to a single process on the remote system. No remote desktop VNC - comes in two flavors of

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

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

Why is figlet source included in xen? Wouldn''t it make more sense to alter xen/Makefile, to have compile.h built from a .in, and the figlet view of the version info, and have the upstream developers regen the figlet part when the version changes? I''m willing to modify the build system to do this. I''m also fixing several other poor implementation of things.

The unstable tree now includes support for SMP guests, i.e. domains which run on multiple cpus. SMP guests can use between 1 and 32 virtual cpus, even if the machine has fewer physical cpus. The code is highly experimental and performance will improve over time. To use SMP guests: - enable option CONFIG_SMP in the Linux 2.6 kernel config - dom0 will boot with upto the number of physical cpus in

hello, I wonder where the Xen''s name came from? I looked at the Xen FAQ, and there is no information.
