Hello:
am trying to get keepalived to work within a VZ container but failing miserably. At the host level within the container config I have:
CAPABILITY="NET_ADMIN:on"
NETIF="ifname=eth0,mac=00:18:51:34:BE:B1,host_ifname=veth205.0,host_mac=00:18:51:31:BD:39,mac_filter=off"
all the necessary ipvs modules have been loaded at the host level:
[root at vsp02 ~]# lsmod | grep vs
ip_vs_wrr 2187 0
ip_vs_wlc 1249 0
ip_vs_sh 1957 0
ip_vs_sed 1249 0
ip_vs_rr 1428 0
ip_vs_pe_sip 2404 0
nf_conntrack_sip 19795 1 ip_vs_pe_sip
ip_vs_nq 1214 0
ip_vs_lc 1182 0
ip_vs_lblcr 5375 0
ip_vs_lblc 4003 0
ip_vs_ftp 3746 0
ip_vs_dh 1893 0
ip_vs 125348 24 ip_vs_wrr,ip_vs_wlc,ip_vs_sh,ip_vs_sed,ip_vs_rr,ip_vs_pe_sip,ip_vs_nq,ip_vs_lc,ip_vs_lblcr,ip_vs_lblc,ip_vs_ftp,ip_vs_dh
ipv6 322593 240 ip_vs,vzrst,ip6table_mangle,ip6t_REJECT,nf_conntrack_ipv6,nf_defrag_ipv6,cnic,ib_addr
and when I check within the container I see:
Apr 11 09:35:56 alb02 Keepalived_vrrp[396]: VRRP_Instance(VI_1) Sending gratuitous ARPs on eth0 for 10.1.8.71
and am able to ping that IP address from with the container. What I cannot do is ping that IP from the host itself so the ARP packets cannot be making out of the container I presume.
has anyone got this working please ?
Thank you, Phil
