Hi , Thanks Christoffer for logging ideas ... I enabled them and left it on for some time and the guest reached the qemu login prompt and froze(cannot actually type root in the prompt) .I saw of a lot of logs showing a softlockup on cpu 0. Here is the final set of logs that I get before the freeze BUG: soft lockup detected on CPU#0!
