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

I'm running a RHEL6 as a development desktop with Fedora 14 (multimedia stuff) and Win XP (corporate email and calendars) running on it as KVM VMs. Everything runs great except for audio pass through. Audio works on the RHEL host. Both VMs see sound cards provided by the VM, but no sound is forthcoming. I have tried adding a PCI audio device from the physical host to the Fedora VM, but then

This patch to the balloon driver eliminates the need for a user-space program to slosh memory between domains and xen. This uses a proc file at /proc/xen/memory_target. When read it reports memory the domain owns in bytes. Writing a new value to the memory_target proc file will cause the domain to exchange memory with xen to reach the target. A xenolinux domain cannot grow bigger than it was

Hi Everyone, I figured out this weekend that Ruby''s Thread implementation causes the Ruby/Event binding I wrote to completely stall and go dead. After reviewing the Ruby source and watching several strace runs, it''s clear that the Ruby Thread implementation uses select in a way that--while not being bad--just isn''t compatible with libevent. The second a thread is

Hi all, I am having confusion regarding the way a newly created domain is allocated vcpu. Initially during dom0 creation alloc_vcpu is called to create vcpu structs for all the available cpu''s and assigned to dom0. But its not the case for domU creation. 1. So how will dom0 relinquish/share vcpu to/with a newly created domU. Does this happen as part of the shared_info page mapping??

I have a xVm b75 server and use zfs for storage (zfs root mirror and a raid-z2 datapool.) I see everywhere that it is recommended to have a lot of memory on a zfs file server... but I also need to relinquish a lot of my memory to be used by the domUs. What would a good value for dom0_mem on a box with 4 gig of ram?

Hi, I am trying to understand Hypervisor_sched_op function and I have few question regarding this - 1. I understand that a guest VM can use the above function with "yield", in order to relinquish CPU time to other guests with running tasks. a) So when the guest VM makes this call does it save/persist any scheduling information about its current processes like runqueue, process state -

I am working on a distributed file system running on linux where I am trying to add support for samba OpLocks and I am observing behavior that I do not understand. My understanding is that samba establishes a lease on a file and expects to receive a signal when conditions change and samba must relinquish the lease. In my file system, when I detect a condition, possibly on another node of my

Hello, I'm using libvirt and sanlock on qemu-kvm guests. Each guest has it's own Logical Volume for it's root filesystem. Sanlock is configured and working and prevents me from starting the same VM twice on multiple nodes and corrupting it's root filesystem. Each VM's domain XML resides on 2 servers that share the LVM volume group over fiber channel. In testing, I noticed

I've mentioned this before but only heard from one other person who has experienced this, but it's becoming a pretty serious issue. The situation: A spammer sets a bot on a fishing attempt to gain email addresses, causing numerous login processes to spawn and suck up all available resources. The problem: Obviously this can act like a dos attack, but the real issue is after the

The ARM platform has no concept of PVMMU and therefor no HYPERVISOR_update_va_mapping et al. Allow this code to be compiled out when not required. In some similar situations (e.g. P2M) we have defined dummy functions to avoid this, however I think we can/should draw the line at dummying out actual hypercalls.

Hi! If there is a string table for section headers, it also gets loaded. Therefore take it into account in size calculation for kernel symtab. Also there is no need to call elf_set_verbose() a second time after elf_init() (First call happens within elf_init()).

...o the Samba Mailing lists, I offered the Samba Team an incentive to initiate a Samba Software Foundation. It looks like the offer was rejected. So, as a gesture of goodwill, in order to demonstrate that i really AM serious about how important I believe it is that an SSF exists, I really really AM relinquishing all copyright of all Samba-related source code that i have ever written, and am placing all that code into the Public Domain. Specifically, but not limited to, that includes the code in samba which made its way into nmbd (dating right back to 1.9.15.p6 and before, and also including the nmbd_multi...

Here''s a question about FE driver and log dirty, when live migration is concerned. Log dirty mode is used in live migration, which works for those polluted pages from CPU issued accesses, but not for DMA path (as BE driver talked here which access from another domain like dom0). Most frontend drivers don''t implement their own suspend interface (netfront implements when
