virNodeGetFreeMemory() returns bytes with Xen driver
by Tyrel Datwyler 18 Apr '09

18 Apr '09

The libvirt API states that the return value of virNodeGetFreeMemory() is in kilobytes. When making this call against a Xen hypervisor and comparing the returned value with what is listed by "xm info" it appears that libvirt is returning the free memory in bytes and not kilobytes. Can anybody confirm this behavior? This code snippet: conn = virConnectOpen("xen:///localhost/"); hostmem = virNodeGetFreeMemory(conn); fprintf(stdout, "Host free memory = %llu\n", hostmem); produces the following output: Host free memory = 3236012032 The following comes from running "xm info" on the Xen host: free_memory : 3086 The libvirt value is convertable into the "xm" returned value if bytes is assumed.

Release of libvirt-cim 0.5.5
by Kaitlin Rupert 16 Apr '09

16 Apr '09

A new release of libvirt-cim is now available at: ftp://libvirt.org/libvirt-cim/ * Features: - Basic network pool creation and deletion - Basic storage pool creation and deletion (directory pools only) - Storage volumes in a pool represented as template ResourceAllocationSettingData - Advertise profiles via SLP * Bug fixes: - Improved reporting: libvirt error is now included in error message returned to the user - ElementConformsToProfile association now supports the RegisteredProfile <--> AllocationCapabilities - Prevent seg fault in get_typed_class() by returning is a NULL value is specified for refcn - Fix xmlgen so XML isn't generated for devices with an UNKNOWN device type - Set the device type of a resource to UNKNOWN after the call to detach_device(), otherwise detach_device() doesn't know what device type to handle - Allow user to specify guest's emulator and expose emulator via the guest's VirtualSystemSettingData - Improve randomization of MAC generation - Determine whether the host system supports KVM or QEMU guests. If KVM support is available, create a KVM guest. Otherwise, create a QEMU guest. - Fix some connection leaks and some libvirt pointer leaks - Be sure to specify the root/virt namespace (instead of root/interop) in ElementConformsToProfile when building the instance of HostSystem

These fixes resolve an occasional hang and and recv error messages seen when running with upstream libvirt. The recv error message is the same one seen in the test run from March 25th on KVM on Fedora rawhide: "libvir: Remote error : cannot recv data: Connection reset by peer"
