Hello,
I've a problem, all my ovirt hosts are linked with a bonding mode 4 (802.3ad LACP) 2x10Gbps Eveything is okay with unix guest but with Windows guest, i can ping but internet browsing is impossible (sometime i have a part of the page, very rare case)
If i remove the bonding and bridge one interface, windows work good.
I've tried with windows 7 and windows 10, guest additions are installed VirtIO / rtl3189 tested, same problem
My bonding opts : mode=4 lacp_rate=1 miimon=100 Interface MTU 9000
Bonding mode 2 also tested
On the hosts, try setting LRO off on the members of your bond, see if it makes a difference eg, ethtool -K ens3f0 lro off ethtool -K ens3f1 lro off Alex -- This message is intended only for the addressee and may contain confidential information.
