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 rel...

...a PCI audio device from the physical host to the Fedora VM, but then it refuses to boot. I remember reading that physical hardware can only be passed through to VMs if it is not in use on the physical host. Any suggestions on how to get audio pass through happening? How can I get the host to "relinquish" the audio device so that a VM can use it? Thanks Michael Hall IT Communications Officer Alice Springs Town Council mhall at astc.nt.gov.au (08) 8950 0561

...e 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 created Ruby assumes it''s the only game in town and doesn''t relinquish control. This basically means that, I have three choices as I see it: 1) Ruby/Event becomes completely evil and redefines Thread''s initialize so that it throws an exception telling you to not use threads. Ugh. 2) Implement DRb using Myriad so that people can get the advantages of t...

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?? 2. Till the end of DOMCTL_createdomain hypercall d->vcpu is null but by the start of xc_linux_bulid_internal function d->vcpu is pointing to some vcpu. How is this?? 3. As part of the domU conf...

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 - runnable, ready etc ? If it does can someone point to the code I can look at. c) When yielded guest VM is...

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 cluster, that requires samba to relinquish the lease, the file system calls linux routine, __break_lease(), on the node where the samba server has established the lease. I would expect that the call to __break...

...red 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 that if I pause a VM on node 1, the sanlock lock is relinquished, and I am able to start the same VM, using the same root filesystem, on node 2. I get a lock error when unpausing node 1's VM if node 2's copy is still running, but by this point, the disk may already be corrupted. Is it necessary that paused VMs don't get to keep their locks? Is...

...cesses 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 spammer stops (by virtue of being added to our firewall blacklist, being caught and shut down by their isp, or otherwise), dovecot doesn't seem to relinquish the resources, causing "too many files open" errors for normal usage. The master process usually hangs around 40-50 files open at any given time, with about 10,000 logins a day (I use: lsof -p `cat /var/run/ dovecot/master.pid ` | wc -l), after the attempt is over I always see the...

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()).

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
