Thanks for response Wes. I have a windows xp running under kvm without using any -net parameters ( I remember reading that -net user is default ) and it works "out of the box". I had assumed that it would be same for windows 2003 server apart from the fact that the kvm wiki website says specific

Hi Haydn, The '-net nic' clause on it's own tells qemu to create a virtual nic in the guest but doesn't tell qemu how to connect it to the host. after '-net nic' you need another -net clause, such as '-net user' to use qemu's internal NAT or '-net tap' to create a tun/tap virtual interface on the

[kvm-devel] [PATCH 2/3] Refactor hypercall infrastructure (v3)

This patch refactors the current hypercall infrastructure to better support live migration and SMP. It eliminates the hypercall page by trapping the UD exception that would occur if you used the wrong hypercall instruction for the underlying architecture and replacing it with the right one lazily.

From: Eddie Dong <[EMAIL PROTECTED]> This patch adds a new vcpu-based IOCTL to save and restore the local apic registers for a single vcpu. The kernel only copies the apic page as a whole, extraction of registers is left to userspace side. On restore, the APIC timer is restarted from the initial c
