VM Stuck in loop with Guest Windows 7

[Fishworm]

Hey Everyone,

We are migrating our VMs from VMware to VirtualBox, hence the simplest way we have found to create .OVF file of the exsisting VM machines in VMware and import it in Virualbox. We have some Windows XP machines and some Windows 7. Windows XP is running very well after conversion, but today I converted one windows 7 VM which has our propietry automation softwares. But it seems to be stuck in loop, It shows Windows Loading Files once or twice then reboots itself. Kindly help me regarding this. Attached is log file.

Thanks in advance

You have allocated waaaay more RAM to the guest than your host has available. You will need to close some applications on the host, reduce the amount of memory allocated to the guest or buy more RAM.
