...s page table pages, and lots of unnecessary page faults occur. The patch will check if the data guest writes to the page table contains valid mfn or not, if not, we believe it is a data page now and then unshadow the page.

hi, It looks that Xen currently only support ISA serial port, which is onboard. Is there any plan to support the PCI serial port?

Hi, I am really confused about NPT walks for guest page table , and eager to know the details about it. It is treated as data writes even if the access itself is a code read in AMD NPT.I just want to know : is it the same in EPT? Could anyone help me? I would like to know that very much Thank you in advance Bo Ma _______________________________________________ Xen-devel mailing list

All, I'd like to plot the main relationship of a grouped data object for all levels of a factor in a single panel. The sample code below creates a separate panel for each level of the factor. I realize that this could be done in other ways, but I'd like to do it via plotting the grouped data object. thanks! dave z = rnorm(18, mean=0, sd=1) x = rep(1:6, 3) y =

Hi,All I searched from git-log, and found that until now we have vhost TX zero-copy experiment feature, how about RX zero-copy? For XEN, net-back also only has TX zero-copy, Is there any reason that RX zero-copy still not implemented? Thanks!
