However, serializing to a file or sockets is very fast for the very same matrix -- hence I wrote this function which runs much faster: .mpi.quick.serialize <- function (object) { fname <- tempfile("Rmpi") stream <- file(fname, "wb") on.exit({ close(stream) file....

Greetings, I have a vm to which I can access using virsh console vm1/ I'd like in addition to be able to dump the serial of the vm in to a file on the host. I've found this https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/6/html/virtualization_administration_guide/sub-section-libvirt-dom-xml-devices-host-interface but it seems that the first second example which

hi again. after some tests, (on my operational domain and on a new testdomain) i detected this behavior: on samba 4.11.6 sometimes the new DNS-records finisches on a wrong dns zone. the problem occurs, if more then 5 records are created with the same name in more then one domain zone for example: testa1.jupiter.mydom.org testa2.jupiter.mydom.org testa3.jupiter.mydom.org

Due to a mistake I created a subdomain with the name of the domain itself. In my case the domain is briesebaer.intern and I created the subdomain briesebaer.intern. Using DNS RSAT Tool I see under briesebaer.intern the subdomain intern and then a recurrence of the whole domain. That means: under intern there is briesebaer and all of the dns query beneath. The query shows the Name=intern

Hello from Vienna, Austria! I'm happily using pxelinux since years. However, I encountered problems on several machines, because they don't boot up properly with PXE. The problem is, that there are recently some devices connected to the serial ports of those machines. pxeboot echoes and listens to the serial console and the output of the menu results in (silly) input back from the

The marilith boxes use a conserver (http://www.conserver.com/) setup for serial access. Our installation exports the logs via http allowing us to grab them with wget. Sending debug keys with is handled separately via xenuse. xenuse ultimately speaks to the conserver too but it abstracts away the IP and port to use so this is preferred. With these changes the correct Serial hostprop for a

This patch adds support for serial output functions. It may be useful for debugging purposes since you can separate ordinary outputs from debugging dumps. Just add "serial.h", and use either serial_print or serial_puts as you would use printf and puts respectivelly. For QEMU, you only need to specify the option -serial stdio. If you use another VM, find how you can redirect the serial

Funny you should post this now. I was just cleaning up some DNS records and the following happend. I had to PTR records with an empty timestamp. I deleted them and wanted to recreate them. My reverse Zones are 0.168.192.in-addr.arpa and 2.168.192.in-addr.arpa both of the records I delted were in the "0" zone. The first i recreated with: samba-tool dns add dc1

Hi- I am having a weird problem with setting dom0 kernel output to the serial console with Xen 3.0.4-1, below is my grub setting. With this setting if I don''t enter the grub menu and have the default boot to the first image, everything works fine and I can get output/input to the serial console. The problem is when I enter the grub menu and select the image to boot from, if I

Hi All. I'm trying to setup a guest within my hypervisor that acts as a Console Server, using 10 USB to Serial adapters. The Host is all setup and can access each Serial Port without problems. I have attempted to add the Serial Connections to a Guest, using both Virtual Machine Manager and by editing the .XML file, and I can add up to 4 Serial devices (Including one for console access to the

Hello, This series fixes a few issues pointed out by Avi and Juan. Avi pointed out we should do full scatter/gather processing of guest data even if current (well-behaved) guests don't send multiple iovs per element. Juan pointed out a few migration-related bugs. In handling the migration fixes, I noticed hot-plug/unplug isn't handled perfectly for the migration case: ports are

So I''ve got an ActiveRecord model pointing to a MySQL db, with an auto-serialized column ("serialize :columnName"). Thing is, MySQL, depending on how it''s configured (like, by default), has a bad habit of just truncating your data if it''s too wide for the column, with no error raised. Yeah, I can probably reconfigure MySQL and/or my AR connection to it. But

Hi, Trying to get vga console and a serial console to both work. I can get either one to fully work but not both. When using serial, I do still get a login prompt on the vga, But not all the boot up output. Seems like half to the vga and the rest to the serial port I added lines to /etc/inittab # console port T0:12345:respawn:/sbin/agetty -L ttyS0 115200 And added to /etc/lilo.conf

Presumably one could stream over the data twice, the first to get the size, without storing the data. Slower but more memory efficient, unless I'm missing something.

USB to USB with standard USB cable will work. If one uses serial to USB adapter on the machine side (to create serial port through USB
