Patching your own boot-disk from first principles
Hi,
I'm trying to build a bootable MSDOS disk and put it on a ISO with floppy and hard disk emulation. I want to use commonly available Linux tools like dd, losetup, mkdosfs, memdisk etc.
I have done the following:
1. dd if=/dev/zero of=myImage bs=1M count=50 [ Builds a 52MB image ]
2. losetup /dev/loop0 myImage [Links /dev/loop0 to myImage file ]
3. vi /grub/stage1; %!xxd; [ NULL the partion

function which saves an image of a dgtMatrix as png
Hi,
I'm getting crazy:
This does work:
library(Matrix)
a1<-b1<-c(1,2)
c1<-rnorm(2)
aDgt<-spMatrix(ncol=3,nrow=3,i=a1,j=b1,x=c1)
png("myImage.png")
image(aDgt)
dev.off()
But this doesn't !!!
f<-function(x){
png("myImage.png")
image(x)
dev.off()
}
f(aDgt)
My image is saved as a text file and contains nothing at all !!!
Thanks in advance,

get the error:

Hi, all.
I searched a lot at mailing list, installed EBImage and gtk packages, but I

Issues with syslinux_run_command(str) and parameters
With the latest 6.03pre I'm seeing an issue where no parameters are passed to the image executed via syslinux_run_command().
An example of this is whichsys.c32, which uses this. E.g., using an example from the wiki page - whichsys.c32 -iso- chain.c32 hd0 -sys- chain.c32 hd1 swap - results in a loop back to the isolinux menu as chain.c32 receives no parameters. Similarly, using -iso- memdisk

Convincing libvirt to create a bridge device?
I was hoping that I could delegate creation of bridge devices to
libvirt for address-less bridges, in order to not have to deal with
the various ways distributions handle persistent network
configuration, but while this creates a libvirt network...
<network>

<forward mode='bridge'/>
<bridge name='brprov'/>

virsh not connecting to libvertd ?
Just found my issue.
After I removed the cephfs mounts it worked!
I will debug ceph.
I assumed because I could touch files on mounted cephfs it was working.
Now virsh list works!

Limitations of macvtap devices?
I am running OpenStack inside a libvirt guest that is connected to the
local network via a macvtap interface. My experience so far suggests
that a macvtap interface will not pass traffic with a source MAC
address other than the MAC address of the interface itself...for
example, if inside the guest eth0 is attached to a bridge.
Is that correct, or is there some setting that will make that work?

Following a suggestion by Henrik Bengtsson I installed EBImage/biocondutor package. I also installed ImageMagick and GTK software because EBImage need it.

myimage<-as.Image(matrix(sample(100*100),nc=100))
