Hi all, I've a simple program called empty.c :) $ cat empty.c int main(int argc, char* argv[]) { return 0; } $ cat empty410.s .file "empty.c" .text .p2align 4,,15 .globl main .type main, @function main: xorl %eax, %eax ret .size main, .-main .ident "GCC: (GNU) 4.1.0 20050922 (experimental)"

Here's a small test program to find out where a klibc executable expects its shared library (or interpreter to be precise) to be. It should work regardless of 32/64 bit, little- or big-endian, but only on native executables. If you have access to a 64-bit or big endian machine, I would appreciate feedback on whether it produces correct answers on your machine. To run the test, cut the

Here is some code i wrote to send a mp3 file to a shoutcast server, with a little modification im sure you could change it and use it to connect to icecast2 and write various things etc... not sure but here it is ------------------------------------------------------ <?php $port = '8000'; $ip = '127.0.0.1'; $fileplay = './whatever.mp3'; $password = 'changme'

Folks -- I''m trying to run FreeBSD 6.0 on a VT-x based Xen system. I''m experiencing a problem where the boot loader is crashing before the FreeBSD kernel (proper) is loaded. The sequence of operations is that the VMX domain is constructed, the BIOS is executed, GRUB loads, I type the instructions to load FreeBSD (a boot loader) and that code begins to execute and then

Under windows all you need to do is edit your php.ini file under C:\WINDOWS\ (xp) or C:\WINNT (2000) Look for the the following lines ;;;;;;;;;;;;;;;;;;;;;; ; Dynamic Extensions ; ;;;;;;;;;;;;;;;;;;;;;; then find ;extension=php_shmop.dll extension=php_sockets.dll ;extension=php_sybase_ct.dll ;extension=php_tokenizer.dll make sure sockets is uncommented you will also need to set the path you

Hello everyone, this is the fourth version of the patch series that introduces ARMv7 with virtualization extensions support in Xen. The series allows Xen and Dom0 to boot on a Cortex-A15 based Versatile Express simulator. See the following announce email for more informations about what we are trying to achieve, as well as the original git history: See

Hi Dave, I remember I read your post, but when I read it, nobody had answered you yet. Thank you very much for the script, it seems to be more complete than mine. I am new to php, to create a script, I usually edit it in notepad and save it as *.php. How can I compile the script '--with-sockets' under windows? Thanks again MAX ________________________________________ From:

Hi, I have a problematic CentOS XEN server and hope someone could point me in the right direction to optimize it a bit. The server runs on a Core2Quad 9300, with 8GB RAM (max motherboard can take, 1U chassis) on an Intel motherboard with a 1TB SATA HDD. dom0 is set to 512MB limit with a few small XEM VM's running: root at zaxen01:[~]$ xm list Name ID

Hi, I''ve not tried pv_ops for a long time but just got a new system (Supermicro X9DRL-iF) so decided to try 3.5.0 with the latest Xen 4.2-unstable, unfortunately the system crashes immediately after loading dom0: traps.c:486:d0 Unhandled invalid opcode fault/trap [#6] on VCPU 0 [ec=0000] I''ve tried loading both bzImage and vmlinuz (gzip compressed vmlinuz) with the same

The PE headers of the generated efi file were quite buggy. And since OVMF perform a few consistency checks, syslinux was unable to run on it. I don't pretend to have a thorough understanding of the PE+ headers, some bugs may remain. :) Celelibi (4): efi: Fix PE header field rva_and_sizes_nr efi: Location, size and alignment of .text section efi: Useless relocations in PE file efi: PE

The following dump-core patches changes its format into ELF, adds PFN-GMFN table, HVM support, and adds experimental IA64 support. - ELF format Program header and note section are adopted. - HVM domain support To know the memory area to dump, XENMEM_set_memory_map is added. XENMEM_memory_map hypercall is for current domain, so new one is created. and hvm domain builder tell xen its

Hi, I installed Syslinux 6.03 on Windows 2008 R2 for PXE Boot. Legacy Boot works fine. In UEFI PXE boot ( files taken from /efi64, syslinux.efi renamed to bootmgfw.efi ) the System boots up into menu correctly. In "default" I configured to either boot efishell.64 or bootx64.efi (Windows PE). But I get following error if I select on to boot: Invalid boot signature 0x00,

Hi it is possible to use xen and spice already? If yes is there any howto or doc how?
