seek(), skip by bits (not by bytes) in binary file
...etc.) and read each chuck
then trash each part that is readBin()'d. Then the last line I get the data
that I want (data1).
Here is my working code:
# I have to read 'junk' bits from the to.read file which is huge integer so
I divide it up and loop through to.read in parts (jb_part).
divr = 20
mod = junk %% divr
jb_part = as.integer(junk/divr)
jb_part_mod = jb_part + mod # catch the remainder/modulus
to.read = file(paste(dbs_path,"/",dbs_file,sep=""),"rb") # connect to the
binary file
# loop in chunks to where I want to be

Using qemu-kvm divre snapshot option
Hi,
looking at the qemu-kvm man page, it is possible to enable
snapshot for a given drive. This is what we need because we would like to start a domain
with two drives, one on a file with snapshot=on and an other drive on LVM with snapshot=off.
Unfortunately it seems that if you use libvirt the same option is not available when you define the domain with a XML file.
I mean, I didn't find
