Are you sure this couldn't be an NFS server problem? Any message or errors in 'dmesg'? Any kernel

Hello, I recently tried Xen 3.0.3-testing on my 2x Opteron-244 SMP machine. Everything works well exept one detail, which is not unimportant to me: the powernow-k8 driver fails to switch frequencies. A closer look on the powernow-k8 source reveals, that some MSR write operations seem to be without any effect. A rdmsr() before and after the wrmsr() call reveals that no real change on the register

Hi, for a RTlinux application I need to install a 2.4.0 kernel. prevoisly, my kernel 2.4.10 was supporting the ext3 fs and all my fs were under ext3. as 2.4.0 doesn't support ext3 I've got a problem to boot cause /proc is recognise as a ext3 fs and my kernel doesnt know how to mount it. what can I do and how to change back /proc to an ext2 fs thanks Fred

Add self pause ability, which is required by vcpu0/dom0 when running on a AP. This can''t be satisfied by existing interface, since the new flag also serves as a sync point.

Hello, CentOS 7.(3) Xen 4.4, Can I find any Doc for selinux with XEN, I found many Problems with selinux on Dom0 ? Or have I to disable selinux when I install XEN. Thank's for a answer. -- mit freundlichen Gr?ssen / best regards G?nther J. Niederwimmer

Hi, As told in "Control Groups Resource Management" libvirt page : Legacy cgroups layout Prior to libvirt 1.0.5, the cgroups layout created by libvirt was different from that described above, and did not allow for administrator customization. Libvirt used a fixed, 3-level hierarchy libvirt/{qemu,lxc}/$VMNAME which was rooted at the point in the hierarchy where libvirtd itself was

Xen/MCE: vMCE injection In our test for win8 guest mce, we find a bug that no matter what SRAO/SRAR error xen inject to win8 guest, it always reboot. The root cause is, current Xen vMCE logic inject vMCE# only to vcpu0, this is not correct for Intel MCE (Under Intel arch, h/w generate MCE# to all CPUs). This patch fix vMCE injection bug, injecting vMCE# to all vcpus. Signed-off-by: Liu,

I''m just doing some testing on the gplpv drivers with different ways of handling interrupts, and I''m trying a scheme where each xen device (eg vbd/vif) driver attaches to the same IRQ as the pci driver, and each handles it in sequence. In testing though, I noticed the following when logging what each ISR is doing: 60.32381439 - evtchn event on port 5 60.32384109 - port 5

Hi keir, In credit scheduler, two vcpus in the same domain may be scheduled on the same CPU. For instance, vcpu0 and vcpu1 are running on the same CPU, vcpu0 is doing spin_lock in guest, then time slice is due, vcpu0 is scheduled out before doing

Since C8.1 kvm guests have a huge delay while booting on a kvm host based on C6. This delay was not present with C8.0. The "pause" happend direct after the grub step. The VNC session shows only a "_" character. Any ideas what changes? -- Leon

Give your RDMSR node type MVT::Glue instead of MVT::Other I tried doing what you said, and the DAG looks like how I think it supposed to look like

Hey, I wanted to add an intrinsics to read MSRs. So I added the intrinsics and lowered it to a new ISD node I created ISD::RDMSR, its first operand is the MSR id. I added a case in X86DAGToDAGISel::Select for ISD::RDMSR. Now I know rdmsr works like so: mov r/ecx, <id> rdmsr r/eax holds the lower 32/64 bit >From what I understood this needs a Token Factor node, nodes which are
