...* cores_per_socket * threads_per_core are broken. The easy fix is to replace those calculations with a new field, nr_cpus in physinfo which is calculated by num_online_cpus(). This patch does so and attempts to change all users over to nr_cpus field in physinfo. This patch touches arch/ia64/xen/dom0_ops.c, but I''ve not done any IA64 testing with this patch applied. -- Ryan Harper Software Engineer; Linux Technology Center IBM Corp., Austin, Tx (512) 838-9253 T/L: 678-9253 ryanh@us.ibm.com diffstat output: tools/python/xen/lowlevel/xc/xc.c | 3 ++- tools/python/xen/xend/Xen...

Hi all, dom0_ops return -EACCES when the interface version in wrong. I think that an acm failure is closer to being non-priv''ed, which returns -EPERM. Wouldn''t want dom0 tools to report they were the wrong version just because ACM limited some operation, surely? Signed-off-by: Rusty Russell &l...

This patch changes the dom0_ops structures as discussed in the thread "32/64-bit hypercall interface". Keir, I added a struct inside XENIF_PTR() to catch direct users in the general code; it was quite useful to have the compiler identify those spots. I have compiled x86_32 and run it with xm-test[1] under qemu. The...

I''ve put together two patches. The first introduces a new dom0_op, set_max_vcpus, which with an associated variable and a check in the VCPUOP handler fixes [1]bug 288. Also included is a new VCPUOP, VCPUOP_create, which handles all of the vcpu creation tasks and leaves initialization and unpausing to VCPUOP_initialize. The separation allows for build-time allo...

Hi, In the case of linux, crash_kexec() is occured by "sysrq c". In the case of DomainU on xen, Help is occured by "sysrq c" now. So The way of dumping DomainU''s memory manualy is nothing. I fix this issue by the following way. 1. Panic is occured by "sysrq c" on both Domain0 and DomainU. 2. On DomainU, coredump is generated in /var/xen/dump (on Domain0).

...terested to see your patch. I guess the "flag" is a reserved bit in the (physical) address passed from kernel to hypervisor? Does that really gain much performance? I guess you will need to do the same thing we need to with privcmd ioctl handling, i.e. copy and modify the pointers in the dom0_op data structures passed to the kernel. :( We need to do one more thing though: we *also* need to change fix up the size of longs and pointers in our code (since 32-bit userland is passing structures to a 64-bit kernel). So perhaps these two fixup passes could be split: we could share the xencomm co...

The paravirtualized guests are offered wallclock time referenced to UTC only, while fully virtualized guests are given the option via the config file (localtime parameter) of starting with UTC time or local time. What would it take to optionally provide localtime to the paravirtualized guests as well? For a guest that launches assuming localtime as its time basis, then later deriving UTC from it

Testing on an 8-node 128-way NUMA machine has exposed a problem with Xen''s nr_cpus calculation. In this case, since Xen cuts off recognized CPUs at 32, the machine appears to have 16 CPUs on the first and second nodes and none on the remaining nodes. Given this asymmetry, the calculation of sockets_per_node (which is later used to calculate nr_cpus) is incorrect:

...d to some > other place? Yep, we''ve had to point people at this work around before. Not nice. I''d really like to see a patch that creates a more fine grained set of privilege capabilities, and an appropriate config file option to set them. For completeness, there should be a dom0_op that enables a domain to irrevocably surrender a capability. There''s an argument that certain capabilities should be specific to a specified target domain or group of domains (we already have a domain group ID). This may be going to far in the first instance, but its worth bearing in min...

Tony Breeds and Rusty''s patches to add make check and make fullcheck allow you to run portions of the hypervisor under valgrind. While doing this, I noticed that there are a lot of places in dom0_ops.c that we''re either not checking the return value of copy_to_user or returning EINVAL instead of EFAULT. The attach patch makes sure wherever we call copy_to_user we check for error and return EFAULT. Regards, Anthony Liguor _______________________________________________ Xen-deve...

Hi Keir, I am interested in changing the max vcpu threshold for a domain while it is running. The following comment in common/dom0_ops.c warns against this: /* * Can only create new VCPUs while the domain is not fully * constructed * (and hence not runnable). Xen needs auditing for races before * removing this check. */ ret = -EINVAL; if ( test_bit(_VCPUF_initialised, &d->vcpu[0]->vcpu_fl...

When you build Xen from source, the "make install" rule installs extra header files such as <xen/xen.h> and <xen/dom0_ops.h> which are all required for building libvirt. However the Debian package doesn't run the install rule, but instead runs (effectively) "make -C tools install" and that only installs a partial set of header files. In particular none of the vital public Xen header files are i...
