Hi folks, currently I try to setup a new xen host v3.4.1 on top of a Asus P5E-VM DO (latest BIOS, Vt-d capable and enabled in BIOS) to migrate my extisting HVMs (Win2k3 server) running on Xen v3.3.0 to a new home. I want to switch over to 3.4.1 to (hopefully!) passthrough my ISDN board to a HVM domU. Unfortunate there seem some issue with the VT-d DMAR tables which is beyond my knowledge and

Hi, I''ve not tried pv_ops for a long time but just got a new system (Supermicro X9DRL-iF) so decided to try 3.5.0 with the latest Xen 4.2-unstable, unfortunately the system crashes immediately after loading dom0: traps.c:486:d0 Unhandled invalid opcode fault/trap [#6] on VCPU 0 [ec=0000] I''ve tried loading both bzImage and vmlinuz (gzip compressed vmlinuz) with the same

TPR shadow/threshold feature is important to speedup the boot time for Windows guest. Besides, it is a must feature for certain VMM. We map virtual APIC page address and TPR threshold from L1 VMCS, and synch it into shadow VMCS in virtual vmentry. If TPR_BELOW_THRESHOLD VM exit is triggered by L2 guest, we inject it into L1 VMM for handling. Besides, this commit fixes an issue for apic access

Hi, I want to run a HVM domU. I have a Dell Optiplex 755: model name : Intel(R) Core(TM)2 Duo CPU E4500 @ 2.20GHz I have enabled VT in BIOS settings under performance. However, after I boot into a linux kernel (not under Xen), grep vmx /proc/cpuinfo returns nothing. When I boot under Xen, I get (XEN) Intel VT-d has been enabled (XEN) [VT-D]iommu.c:1700: Queued Invalidation hardware not

After further investigation: `xm dmesg' output: (XEN) CPU0: VMX disabled by BIOS. (XEN) VMX: failed to initialise. I tried the following: - updated to the latest BIOS 2.21 from Lenovo - reboot and press `ThinkVantage' button - under CPU, enable VMX Rebooting into Xen, it still didn't work After reading about this in search results, I found that many users have had to do a cold

Greetings, I''m attempting to do gfx_passthru with the primary graphics adapter (03:00.0), passing it to a guest. I can unbind it from the host but when I fire up the guest OS my monitor loses signal from the graphics card and that''s that. The GFX card is dual DVI, I''ve tried both slots. Host is Linux 2.6.32.14-1.2.105.xendom0.fc12.x86_64, Guest is Windows 7. PC is an

I am trying to connect a KVM-QEMU VM to OVS-DPDK vhostuser port. But, I am encountering a few errors. Since I am very new to libvrt and Linux I am not able to sort them out. Any guidance in this regard would be a great help.

From: Nicu?or C??u <ncitu at bitdefender.com> This is preparatory patch to mediate the MSR interception between the introspection tool and the device manager (one must not disable the interception if the other one has enabled the interception).

Thanks for your advice. I will re-organize the patch.

Some operating systems access the local APIC TPR very frequently, and we handle that using software-based local APIC virtualization in Xen today. Such virtualization incurs a number of VM exits from the memory-access instructions against the APIC page in the guest. The attached patch enables the TPR shadow feature that provides APIC TPR virtualization in hardware. Our tests indicate it can

From: Yang Zhang <yang.z.zhang@Intel.com> The following patches fix the issue that fail to boot L2 guest on APIC-v available machine. The main problem is that with APIC-v, virtual interrupt inject L1 is totally through APIC-v. But if virtual interrupt is arrived when L2 is running, L1 will detect interrupt through vmexit with reason external interrupt. If this happens, we should update

Hi, I am having some issues with xen hypervisor crashing because it could not find one of the cores in my processor. This is not consistent. It happens once in every two or three boots. Is this is xen bug or is it something related to BIOS. If it is a xen bug, has it been addressed and could you point me to the right patch. Here is the xen boot message. title CentOS (2.6.18-274.7.1.el5xen)

VT is enabled in BIOS and ''xm info'' shows that hvm can be created like below: xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm -3.0-x86_64 Several Windows VMs have been created on this server and running perfectly. However, I wonder that it does not show anything when commands show VT-x availability such as ''xm dmesg | grep VMX(or

Change from v2: re-written code in ''vmx_intr_assist'' into if()/else if() sequence to make code change easy to review. Virtual interrupt delivery avoids Xen to inject vAPIC interrupts manually, which is fully taken care of by the hardware. This needs some special awareness into existing interrupr injection path: For pending interrupt from vLAPIC, instead of direct injection, we
