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

Serial ports: vm vs bare metal
I'm running libvirt under Fedora 28. I would like to attach a USB
device to a VM, but when I select "Redirect USB Device" from the
"Virtual Machine" menu in virt-manager and then select the device, I
get the error:
USB redirection error

virsh attach device equivalent in libvirt API
Hi,
Is there an equivalent of "virsh attach-device -live -persistent " within libvirt API :
virDomainAttachDevice() or virDomainAttachDeviceFlags() or ???
Thanks for help.

Ah, this is on F23, which has:

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

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,

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!
thanks

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?

Hi, all.
I searched a lot at mailing list, installed EBImage and gtk packages, but I
couldn't make this simple work:

Well, that certainly solves my problem with vol-download :). Do you
know if that fix is likely to show up in EL7?

Buggy 1.3.2? Disconnected from qemu:///session due to I/O error

How do I close a console connection?
I'm working on (re-) implementing serial console support in virtualbmc

establishing a console connection via...
self._stream = self._conn.newStream(libvirt.VIR_STREAM_NONBLOCK)
self._domain.openConsole(None, self._stream, 0)
...I can't figure out how to close the console. Subsequent calls to

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
