[-- Attachment #1 --] Hello all, it seems to me that there is some room to improve how are things about networking reported from FreeBSD VM to the hypervisor. Now we have function xe_ip_if() in /usr/local/sbin/xe-update-guest-attrs which just grep for xn interfaces, read one IP address for each which is eventually written to the /var/cache/xenstore/attr/ethNUMBER/ip First - from where the ip node comes? I didn't find any such in https://xenbits.xen.org/docs/unstable/misc/xenstore-paths.html We have xenstore ls attr eth0 = "" ip = "10.0.0.1" PVAddons = "" MajorVersion = "6" MinorVersion = "2" MicroVersion = "0" BuildVersion = "76888" Installed = "1" But on Linux xenstore ls | grep attr -A 50 attr = "" PVAddons = "" BuildVersion = "1" Installed = "1" MajorVersion = "8" MinorVersion = "1" MicroVersion = "50" vif = "" 1 = "" ipv6 = "" 0 = "fe80::9c30:52ff:fef1:8711" ipv4 = "" 0 = "10.128.99.15" 2 = "" ipv4 = "" 0 = "10.0.1.15" ipv6 = "" 0 = "fe80::e833:9cff:fe5e:c21c" 0 = "" ipv4 = "" 0 = "172.22.1.15" ipv6 = "" 0 = "fe80::c0ff:d7ff:fee2:b5ff" xenserver = "" attr = "" device = "" vbd3 = "" 768 = "" 5696 = "" vif = "" 0 = "" static-ip-setting = "" mac = "c2:ff:d7:e2:b5:ff" error-code = "0" error-msg = "" enabled = "0" enabled6 = "0" 1 = "" static-ip-setting = "" mac = "9e:30:52:f1:87:11" error-code = "0" error-msg = "" enabled = "0" enabled6 = "0" 2 = "" static-ip-setting = "" mac = "ea:33:9c:5e:c2:1c" error-code = "0" error-msg = "" enabled = "0" enabled6 = "0" And secondly - I have multiple interfaces in VM, renamed by VLANs their are connected to. Some of them have multiple IPv4 addresses. Some also have IPv6 address(es). Bummer, I don't see any of this in pool management. And I wouldn't even without interface renames, because we report only one IPv4 address. First problem may be solved with some creative work with /etc/rc.conf, for example using result of following command in adition to simple ifconfig | grep xn sysrc -a | grep -E "ifconfig_xn[[:digit:]]_name" ifconfig_xn0_name: vlan1000 ifconfig_xn1_name: vlan1001 ifconfig_xn2_name: vlan2000 or list all ethernet interfaces (ifconfig -l ether) and look for ifconfig_xnX_name line for each not(xn). But regarding other missing info/nodes, I just don't know. May someone please enlighten me what is missing on our side? uname -a FreeBSD hostname 13.1-RELEASE FreeBSD 13.1-RELEASE releng/13.1-n250148-fc952ac2212 GENERIC amd64 pkg info xe\* xe-guest-utilities-6.2.0_3 xen-guest-tools-4.14.0 -- Best regards Ondra Knezour [-- Attachment #2 --] 0 *H 010 `He 0 *H 000 *H 0e1 0 UCZ10UaNTRCZ-471149831 0U Česká pošta, s.p.1 0 UPostSignum Root QCA 40 180927073923Z 330927073923Z0i1 0 UCZ10UaNTRCZ-471149831 0U Česká pošta, s.p.1"0 UPostSignum Qualified CA 40"0 *H 0 rm2v<b MR.`sE 4 JWN7$> ]x i䃊O`R:4u¦[DcaH(0h,r;\xֽ* UFWn V'CԬ۩`R- %#v.. /|۴[/^̇3j EEק.5_ QDFk7;X:I[/ &zؐjhN =HFAri 8hqiIŧl[NIFFb60&6S1o Y߶? $:.f.fZ:/U$w -JrqEGH/Do䃁_Tˏ ?C r& P/fM'^H*._ w\df^)iy,Zp1Tw Ԓ|2ɸ{D;r!)pu`?#u?Rd>D d0`0U 00U 00+0Tento certifikat pro elektronickou pecet byl vydan v souladu s narizenim EU c. 910/2014.This is a certificate for electronic seal according to Regulation (EU) No 910/2014.0U 0 0z+n0l07+0+http://crt.postsignum.cz/crt/psrootqca4.crt01+0%http://ocsp.postsignum.cz/OCSP/RQCA4/0U 0 U #06 ipQ5O?P~&) 0U 001/-+http://crl.postsignum.cz/crl/psrootqca4.crl020.,http://crl2.postsignum.cz/crl/psrootqca4.crl01/-+http://crl.postsignum.eu/crl/psrootqca4.crl0 U (|>6 8P=!`\ax0 *H ,bt8+qj:0`C s+Jrg 'i=_'1t0dݮ7X<0.O2%(4[ث"lQ!Rll|M>LIkEߒ*T,?xe-M&4M~~hhϸaemYgzP4leZ-}{ $CVh Be!G|6Eyz_<O51oy g3E^9j2ocƭòV=Q}E,rdʷWHwFx%0{#ƌ) ۥl f= N0dF|oںY 0 5#8eוt4{?L6lFSeSVrO_AXcD8,,"g Jq 浵UtH (on )%O$QJִL6%9"Q m 8y>'* d x켧7`GWc>=HKq jn#uwZ40M05V0 *H 0i1 0 UCZ10UaNTRCZ-471149831 0U Česká pošta, s.p.1"0 UPostSignum Qualified CA 40 210831020041Z 220920020041Z01 0 UCZ10UaNTRCZ-6888548210U Ondřej Kněžour1 0U 110U Ondřej Kněžour10U Kněžour10U* Ondřej10 UP182360"0 *H 0 Q Q1m͠ ( Vw h%#37L߅y,)b\Yt tT@,2zs{{=f%'O`̴Z ufzJiB̩DST7*'] {.S\2kW?cPd 8eWo fwjպ QBGv^2TK% '{v܂+kX6>2h hv r!IǢR6q8%~wa 00?U 806knezour@weboutsourcing.cz + 11289118610 U 0 0,U #0 0 gH00+0Tento kvalifikovany certifikat pro elektronicky podpis byl vydan v souladu s narizenim EU c. 910/2014.This is a qualified certificate for electronic signature according to Regulation (EU) No 910/2014.0$+http://www.postsignum.cz0 @ 0+00 F0j F0`0.(https://www.postsignum.cz/pds/pds_en.pdfen0.(https://www.postsignum.cz/pds/pds_cs.pdfcs0 F0 F0}+q0o0;+0/http://crt.postsignum.cz/crt/psqualifiedca4.crt00+0$http://ocsp.postsignum.cz/OCSP/QCA4/0U 0 U %0+ +7 0 U #0(|>6 8P=!`\ax0U 00531/http://crl.postsignum.cz/crl/psqualifiedca4.crl06420http://crl2.postsignum.cz/crl/psqualifiedca4.crl0531/http://crl.postsignum.eu/crl/psqualifiedca4.crl0 U ˛A N8s0/,-6zo7p?%0 *H pmN'߀>]PٺpםƮ@JVow_qdʑ5e'G<C}x5nKuتXqR|gNn5u ÚHt2+gBޒ YCɯcc}@eNV Q3dҝغ34091e qwT %`˅ݧ J"-;cyQ9{'Z5Pϸ8(5uex-$7 / Mr'MzB@ vѱn8C)XL8B+\9=f_imWb5BRdدx@\{%$IWvߪUɽ }TWh7jza6lHןowp :U a pk1Y?q Ƴޭ7h /= 2}Y]QK)TD#rf7*10{0q0i1 0 UCZ10UaNTRCZ-471149831 0U Česká pošta, s.p.1"0 UPostSignum Qualified CA 4V0 `He 0 *H 1 *H 0 *H 1 220805134356Z0/ *H 1" rRj`\xēQg Y"0l *H 1_0]0 `He*0 `He0 *H 0*H 0 *H @0+0 *H (0 +71s0q0i1 0 UCZ10UaNTRCZ-471149831 0U Česká pošta, s.p.1"0 UPostSignum Qualified CA 4V0 *H 1sq0i1 0 UCZ10UaNTRCZ-471149831 0U Česká pošta, s.p.1"0 UPostSignum Qualified CA 4V0 *H 0Y|qIԖJgCۉ"Xi' I#R[JF\* + N|lPD&&O|T ND03Gl4p;CnM^֪md B,Hmf'_j+!
