I tried latest xen and linux-xen staging tree, but failed to run HVM domain on x86-64 environment. domU creation is OK. However the weird thing is not HVM domain itself. Instead system crashed on dom0 context. I saw once with some stack dump that xen''s page fault handler is executed on a dom0''s stack which then causes nested page fault due to unable to fetch vcpu pointer.

We cannot startup IA32/IA32pae unmodified linux guest OS. Booting 32bit VMX domain will stop at printing "ACPI: Unable to locate RSDP". Booting 32pae VMX domain will get a kernel panic. No abnormal info found in serial output. It''s interesting that sometime we can boot Windows 2003. Booting Windows SP1/SP2 Guest will crash with attached serial output. Bests Jeff

Hello, I need 6 virtual interfaces in a domU (which will be our firewall). I''ve created 6 bridges in dom0, configured everything correctly... When I start the domU, it can only see 3 of them : eth0, eth1, eth2. However, the bridges in dom0 are correctly configured, and I can see all 6 vifs (from vif<DOM_ID>.0 to vif<DOM_ID>.5) when using "brctl show". On the

After much ado about the naming of model adn controllers... model : Expense controller : Expenses route : map.resources :expenses Here I am using mysql database and created a unique index, since db:migrated created an id object and made it as primary key. Now in the def create @expense = Expense.new(params[:expense]) if @expense.save flash[:viola] = ''New expense saved.. be

I have a view where I render a partial over a collection. Each instance of the partial includes a <div> with an id specific to that instance. Inside the partial, there is a select tag for "year". I''m trying to change some of the contents of the partial when user changes the year. I''m using this in the view: <%= select_tag :year,

For an SMP Linux HVM guest with PV drivers inserted, when we do save/restore (or LiveMigration) for the guest, it might panic after it''s restored. The panic point is inside ap_suspend(): .... while (info->do_spin) { cpu_relax(); read_lock(&suspend_lock); HYPERVISOR_yield(); ----> guest might panic on the invocation of this function.

Hi all, This is the test report of xen-unstable tree. There are one bug found. Version Info: ================================================================= xen-changeset: 25256 Dom0: linux.git 3.1.0-rc7 (commit: d93dc5c...) ================================================================= New issue(1) ============== 1. cpu weight out of range error when create hvm domU

Hi, I''m getting a conflict between the Mocha plugin and the Rails SimplyHelpful plugin. For some reason the dom_id method from SimplyHelpful is not being found in my views when the Mocha plugin is installed. The dom_id method if used in the controller works properly. This is the error I get when running the tests: 1) Error: test_truth(HmmControllerTest):

It seems common to use RJS for quickly adding and highlighting a list that is having content added to it like this: http://rafb.net/paste/results/Z3m32g48.html ... where "my_list" would be an UL and the partial would insert a LI. Given that example, is there an easy way to highlight only the newly inserted LI instead of the whole UL? The only way I can see to do it is to give

Hi, I''m very new to rspec so please be patient with me. I''ve tried to take some of my tests out of the controller specs to check for things that are rendered. This has not worked so well, since my views have the controller method current_user in quite a few places. Is there any way that I can define this so that my views will be executed? Will this same thing occur for all

The patch moves the struct IO_APIC_route_entry to a common place. This allows us to share the struct with iosapic. Thanks, -- Dexuan _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

I think we need this feature at least for debugging purpose, right? Or, do we already have this feature? Thanks, Neo -- I would remember that if researchers were not ambitious probably today we haven''t the technology we are using! _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

The datasheet is available at http://download.intel.com/design/network/datashts/82599_datasheet.pdf See 'Table 9.7. VF PCIe Configuration Space' of the datasheet, the PCI Express Capability Structure of the VF of Intel 82599 10GbE Controller looks trivial, e.g., the PCI Express Capabilities Register is 0, so the Capability Version is 0 and pt_pcie_size_init() would fail. We should not

In x64 SMP Vista HVM guest (vcpus=2 in the configuration file), the wall clock time is 50% slower than that in the real world.

Changeset 15046:e527b4ff1948 breaks 32-bit HVM guest: when req->size is 4, "1UL << 32" returns 1 in IA32 system, so the mask becomes 0 wrongly. The attached patch fixes this by using 64-bit left-shift.

Hello, I''m also seeing this exact same problem. I''ve posted on xen-users, but did not get an answer. Venkat seems to be experiencing the same problem as me. I have the latest BIOS for my motherboard DQ35JO. (BIOS ver 933) I''m running a Q6600 as well. It hangs at "Brought up 4 CPUs." I''ve tried all sorts of combinations of Xen versions and kernels to

Currently, Xen does not support injecting an NMI to HVM guest OS. Adding this feature is necessary for those softwares which depend on NMI to function correctly, such as KDB and oprofile. The attached patch allows NMI to be injected to guest OS in NMIP capable platforms. It also enables to queue an NMI and then inject it as soon as possible. Signed-off-by: Haitao Shan

This adds a boolean boot parameter to xen to allow reserved memory regions to be added to the iommu mappings for dom0. The parameter is "iommu_include_reserved" and is off by default. A warning is also traced when incorrect RMRR to system memory map values are detected. This is being added to address some incorrect BIOS''s that do not report correctly the requied reserved memory

Hi, all, The attached patches try to improve the current FLR logic. The idea is: removing the FLR logic from hypervisor and adding the improved logic in Control Panel. The current FLR logic in hypervisor has some issues: 1) Dstate transition is not guaranteed to properly clear the device state; 2) the current code for PCIe FLR is actually buggy: PCI_EXP_DEVSTA_TRPND doesn''t mean the
