Ian, Keir, This patch is to boot 32-bit VMX guest on the 64-bit host. Double-compile is used to make both 64-bit guest and 32-bit guest can work, the shadow page-table uses current 64-bit shadow code''s structure to simulate 32-bit guest''s 2-level page-table.

To avoid MSR save/restore at every VM exit/entry time, we restore the x86_64 specific MSRs at domain switch time if modified. In VMX domains, we modify those upon requests from the guests to that end. Note that IA32_EFER.LME and IA32_EFER.LMA are saved/restored by H/W on every VM exit. For the usual domains (i.e. dom0 and domU), those MSRs are not modified once set at initialization time, so we

Hi Kashyap, Here I want to test and see how much I/O performance could be improved by virtio-blk data plane feature. Yes, this is a dirty way to enable it :-), You mentioned using newer libvirt, is there parameter similar "x-data-plane=on" in new version libvirt? Please let know me you if you have better solution.

Hi Eric, Thanks! You are right, I missed declaring namespace, now, the <qemu:commandline> is saved after virsh edit. However, both namespace and <qemu:commandline> tag are lost after I run "nova start" to launch the VM. Any idea that how could I make this qemu command take effect ? Regards, CY.

Hi, I was running libvirt 1.2.2 and qemu 2.0 which are from icehouse cloud archive repo on ubuntu 12.04, "virsh list --all" showed correct instances after launching several VMs, Then I just downgraded libvirt to 0.9.13 and qemu to 1.0, but kept the VMs running. However, when I run "virsh list --all" after downgrade, I can't see any VMs. Seems that the old version libvirt

Hi There. I am in the process of "upgrading" my Xen 2.0.7 server with a Xen 3.0.2, though I am doing so on a different machine. My firewall will be running as a DomU, asit also does on the existing server. The new server is Ubuntu 6.06 and the existing server is Debian Sarge. On the existing server, I have the WAN interface hidden from Dom0 with the two other physical interfaces

Hi, I tried to enable virtio-blk data plane feature for VMs in my openstack environment, the hypervisor is ubuntu 14.04, libvirt 1.2.2 and QEMU 2.0. As nova doesn't support that parameter yet, I did belows 1. nova boot a VM with raw disk image. 2. nova stop the VM. 3. run "virsh edit <instance-id>" on the hyprvisor node, and adding below into instance xml just before

Basic infrastructure for Xen S3 support with a common CPU context save/restore logic for both 32bit and 64bit. Wakeup code is split into two parts: - the first locates after trampoline code, to share all the tricks on the latter, like relocation base and identy mapping - the 2nd part locates in xen code segment, to do the actual CPU context restore Signed-off-by Ke Yu

Can you please check the vcpu status? I suspect one of the vcpu is blocked by halt instruction.

In debugging the sles9 port on 64 bit MP machines, I am seeing a problem where the hypervisor takes a fault in loading fs in the context switch code (load_segments()). The selector is one of the TLS selectors. It appears that the cpu in question has updated this selector with a value of 0 just prior to the problem I am seeing. Looking at the Linux context switch code, we first update the TLS
