Re: [libvirt] [PATCH] hostdev: fix net config restore error

Fix for such a case: 1. Domain A and B xml contain the same SRIOV net hostdev(<interface type='hostdev' /> with same pci address). 2. virsh start A (Successfully, and configure the SRIOV net with custom mac) 3. virsh start B (Fail because of the hostdev used by domain A or other reason.) In step 3, 'virHostdevNetConfigRestore' is called for the hostdev which is still used by domain A. It makes the mac/vlan of the SRIOV net change. Code Change in this fix: 1. As the pci used by other domain have been removed from 'pcidevs' in previous loop, we only restore the nic config for the hostdev still in 'pcidevs'(used by this domain) 2. wrap a function 'virHostdevIsPCINetDevice', which detect whether the hostdev is a pci net device or not. 3. update the comments to make it more clear Signed-off-by: Huanle Han <hanxueluo(a)gmail.com&gt; --- src/util/virhostdev.c | 70 ++++++++++++++++++++++++++++++++++----------------- 1 file changed, 47 insertions(+), 23 deletions(-)
