Hi Stefano, Thanks for your response. Please find my responses inline. On Mon, Sep 27, 2010 at 3:52 PM, Stefano Stabellini <stefano.stabellini@xxxxxxxxxxxxx> wrote:
I will use the latest branch. Also make sure that the PV interfaces are actually running, in Could you please let me know where(config file) can I configure/verify the name for root device. Since I am testing network performance, I verified which network interface is used in the PV-on-HVM VM. I found that there is no Ethernet device displayed in the lspci output of VM. Here is the lspci output on PV-on-HVM VM. The Xen platform device is displayed in lspci. This means that the
platform device is used as PV driver in the PV-on-HVM guest. Please
correct me if I am wrong. =========================================================== 00:00.0 Host bridge: Intel Corporation 440FX - 82441FX PMC [Natoma] (rev 02) 00:01.0 ISA bridge: Intel Corporation 82371SB PIIX3 ISA [Natoma/Triton II] 00:01.1 IDE interface: Intel Corporation 82371SB PIIX3 IDE [Natoma/Triton II] 00:01.2 USB Controller: Intel Corporation 82371SB PIIX3 USB [Natoma/Triton II] (rev 01) 00:01.3 Bridge: Intel Corporation 82371AB/EB/MB PIIX4 ACPI (rev 01) 00:02.0 VGA compatible controller: Cirrus Logic GD 5446 00:03.0 Class ff80: XenSource, Inc.
