Re: [kvm-devel] multiple allocation for vmcs or am i missing something.

Thus I don't think that vmcs area is allocated twice for each vcpu. Regards, Guillaume - Using Tomcat but need to do more? Need to support web services, security?

Re: [kvm-devel] KVM-13 and 2.6.20 kvm and kvm-intel
Hi,
Iain Kyte wrote:
What has made the KVM-13 stop working with Linux 2.6.20 kvm and kvm-intel?
API has been modified.
As said Avi in kvm-13 release note : if you use the modules from Linux 2.6.20,
you need to use kvm-12.
You can also apply attached patch on linux-2.6.20 source tree (it's just a copy
of kvm-13 in linux-2.6.20/drivers/kernel)
Regards,
Laurent

[kvm-devel] Xenoppix (KNOPPIX5.1.1 + Xen3.0.4 + QEMU/KVM + HTTP-FUSE) is released
Dear, We released new Xenoppix which is consisted of KNOPPIX5.1.1, Xen3.0.4, QEMU/KVM, and HTTP-FUSE(stackable/network virtual disk). You can compare Xen(3.0.4 on Linux2.6.16) and KVM(Release 12 on Linux2.6.19) on the CD-ROM. The boot of CD image is accelerated by LCAT. http://www.alpha.co.jp/biz/rdg/ac-knoppix/index_en.html === ### New Feature (chagelog) - KNOPPIX is upgraded to 5.1.1(Japanese Edition) and Xen is upgraded to 3.0.4. GRUB Menu includes two items; Xen3.04(kenrel 2.6.16.33) and normal KNOPPIX (kernel 2.6.19). Xen3.0.4 improved support for SMP and ACPI. The feature enables to merge previous EFI version and normal BIOS version. -konppixHMV command runs KNOPPIX on a full virtualization on IntelVT/AMD-V. -knoppixU command runs KNOPPIX on a para virtualization. - KVM(Kernel based Virtual Machine) is included. The version is Release 12 2007-01-23 on Linux 2.6.19. -QEMU/KVM is runnable on IntelVT/AMD-V with kvm command. If IntelVT/AMD-V isn't on, the window bar shows QEMU. - [Experimental] HTTP-FUSE (stackable/network virtual disk) -It enables to boot Debian/GNU Linux Etch on Xen form Internet. -HTTP-FUSE CLOOP is stackable/network virtual disk.

Re: [kvm-devel] Now that 2.6.20 is out
Hi Avi, what guest? what host? Guest and host == ubuntu 6.10 host = Intel VT It fails on Qemu start up, which shows a black screen and terminate with the exception 13 (0) error. I read somewhere that this is due to the Intel VT inability to handle real mode, is this the case? Most chances are that this is the case. You can shift to a textual boot loading and it should work.
