      virsh: fixing segfault by pool autocompleter function. · 8fe09a53
      由 Julio Faracco 提交于 
      The commands which requires a pool to perform any action for a volume is
throwing a segfault when you pass the volume name before a pool name or
without the argument '--pool'.

An example that works:
virsh # vol-list loops-pool
 Name                 Path
-------------------------------------------------------------------
 loop0                /mnt/loop0

virsh # vol-info --pool loops-pool lo<TAB>

An example that does not work:
virsh # vol-list loops-pool
 Name                 Path
-------------------------------------------------------------------
 loop0                /mnt/loop0

virsh # vol-info lo<TAB>
Segmentation Fault

The example 'vol-info' can be executed as 'vol-info loop0 --pool
loops-pool'. So, this commit fixes this problem when the arguments are
inverted and avoids the segfault.

      nwfilter: save error from DHCP snoop thread to report in main thread · 1297db74
      由 Laine Stump 提交于 
      A problem encountered due to a bug in libpcap was reported to the
caller as:

   An error occurred, but the cause is unknown

This was because the error had been logged in the DHCPSnoop
thread. The worker thread handling the API call to start a domain
spins up the DHCPSnoop thread which watches for dhcp packets with
libpcap, then uses virCondSignal() to notify the worker thread (which
has been waiting with virCondWait()). The worker thread knows that
there was an error (because threadStatus != THREAD_STATUS_OK), but the
error info had been stored in thread-specific storage for the other
thread, so the worker thread can only report that there was a failure,
but it doesn't know why.

The solution is to save the error that was logged (with
virErrorPreserveLast() into the object the is used to share info
between the threads, then we can set the error in the worker thread
using virErrorRestore().

In the case of the error I was looking at, this changed the "unknown"
message into:

    internal error: pcap_setfilter: can't remove kernel filter:
    Bad file descriptor

      libxl: round memory values to next 1MiB increment · ef71caea
      由 Jim Fehlig 提交于 
      libxl requires the memory sizes to be rounded to 1MiB increments.
Attempting to start a domain that violates this requirement will
fail with the marginally helpful error

2018-02-22 01:55:32.921+0000: xc: panic: xc_dom_boot.c:141: xc_dom_boot_mem_init: can't allocate low memory for domain: Out of memory
2018-02-22 01:55:32.921+0000: libxl: libxl_dom.c:671:libxl__build_dom: xc_dom_boot_mem_init failed: No such file or directory

Round the maximum and current memory values to the next 1MiB
increment when generating the libxl_domain_config object.
