similar to: [PATCH]Fix the boot of ia32pae Windows xp guest (up acpi)

Hi, Keir, This attached patch fixes the issue that guest can not boot if set empty cdrom in configuration file. (For example, disk = [ ''file:/images/a.img'', '',hdc:cdrom,r'' ]) This is because function "uname = config.get(''uname'', '''')" returns '''' but not None if uname is not in config

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

Hi, Keir, This patch is to fix the problem of Linux guest installation failure and Windows 2000 boot failure.       In the early code, we use vmx_vmexit_handler() -> vmx_io_instruction() function to emulate I/O instructions. But now, we use vmx_vmexit_handler() -> handle_mmio -> hvm_emulate_one() -> x86_emulate() to emulate I/O instructions. Also nowadays, the realmode

- use __clear_bit() rather than clear_bit() - use switch statements instead of long series of if-s - eliminate pointless casts (Applies cleanly only on top of the previously sent SVM/EFER patch.)

Backport upstream kernel patch to fix Dom0''s bad pte bug. - In Dom0 kernel, at boot time, system will call bt_ioremap() to do mappings for the Boot Time Fix Memory region. Also system will call bt_iounmap() to unmap the memory region by setting phys=0. In this case, system will encounter pte_ERROR(). This patch backports the upstream kernel patch by Ingo Molnar <mingo@elte.hu>,

Fix the return value of blkdev_name_to_number(). - Function blkdev_name_to_number() should return both devname and devnum, otherwise it may cause "unpack non-sequence" error.

Hi list, I don't know whether this is the right place for sending patches. While integrating flac into our yocto project "www.yoctoproject.org", we found a build issue in flac/examples. The following patch fixes this issue. BTW, is flac still under maintenance? I saw it was not upgraded for a long time. Thanks, Dongxiao Fixes no declaration of memcmp(). Signed-off-by: Dongxiao

The previous order of relinquish resource is: relinquish_domain_resources() -> vcpu_destroy() -> nvmx_vcpu_destroy(). However some L1 resources like nv_vvmcx and io_bitmaps are free in nvmx_vcpu_destroy(), therefore the relinquish_domain_resources() will not reduce the refcnt of the domain to 0, therefore the latter vcpu release functions will not be called. To fix this issue, we need to

Netback: Multiple tasklets support. Now netback uses one pair of tasklets for Tx/Rx data transaction. Netback tasklet could only run at one CPU at a time, and it is used to serve all the netfronts. Therefore it has become a performance bottle neck. This patch is to use multiple tasklet pairs to replace the current single pair in dom0. Assuming that Dom0 has CPUNR VCPUs, we define CPUNR kinds of

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

Changes from v1 to v2: - Use a macro to replace the hardcode in patch 1/3. This patchset fixes issues about IA32_VMX_MISC MSR emulation, VMCS guest area synchronization about PAGE_FAULT_ERROR_CODE_MASK/PAGE_FAULT_ERROR_CODE_MATCH, and CR0/CR4 emulation.

Changes from v2 to v3: - Use pfn_to_paddr() to get the address from frame number instead of doing shift directly. - Remove some unnecessary initialization code and add "static" to vmentry_fields and gpdptr_fields. - Enable the VMREAD/VMWRITE bitmap only if nested hvm is enabled. - Use clear_page() to set all 0 to the page instead of memset(). - Use domheap to allocate the

Hi list, Recently I was debugging L2 guest slow booting issue in nested virtualization environment (both L0 and L1 hypervisors are all Xen). To boot a L2 Linux guest (RHEL6u2), it will need to wait more than 3 minutes after grub loaded, I did some profile, and see guest is doing disk operations by int13 BIOS procedure. Even not consider the nested case, I saw there is a bug reporting normal VM
