<div dir="ltr">Hi,<div><br></div><div>I am trying to launch lguest on a lguest enabled kernel for Samsung Galaxy Tab 3. When I launch lguest, the start-up hangs at a certain point indicated in the log below. </div><div><br>
</div><div>I have attached the .config file I used to build the kernel (3.4.34 with modifications by Samsung) and also the host kernel start-up log. I have read that the highmem option has to be set to either 4g or none, but these settings prevented the host kernel from booting up. I am currently trying to build lguest with highmem set to 64g. Could someone please let me know if the hang during the start-up is due this setting mismatch ? (I am trying to launch lguest with only 128 MB memory, which I think is indicated in the log below)</div>
<div><br></div><div>Also attached the host kernel's startup log. </div><div><br></div><div>Thanks,</div><div>-Ajit</div><div><br></div><div>----------------------------------------------------------------------------------------------------------------------------</div>
