Re: MS DNS doesn't answer to CURRENT under Hyper-V
Hi! I see you have done the code for disabling UDP checksum offloading when running on the Hyper-V on Windows Server 2012 and earlier hosts https://svnweb.freebsd.org/base?view=revision&revision=285785 I tried new CURRENT and it works. Thank you!

Ok, r284746 is the root of the problem. MS DNS works under r284745 and doesn't work under r284746.

Re: MS DNS doesn't answer to CURRENT under Hyper-V
Well, turning off checksum offloading by `ifconfig hn0 -txcsum -rxcsum` definitely helps. As for tcpdump I'm not completely sure if I did it right, but I see "bad udp cksum" phrase: # tcpdump -i hn0 -vvv -nn udp dst port 53 tcpdump: listening on hn0, link-type EN10MB (Ethernet), capture size 262144 bytes 18:01:19.139994 IP (tos 0x0, ttl 64, id 61218, offset 0, flags [none], proto UDP (17), length 51) 192.168.25.26.45683 > 192.168.25.3.53: [bad udp cksum 0xb39e -> 0xf210!] 52886+ A? ya.ru.

MS DNS doesn't answer to CURRENT under Hyper-V
Hi! I have a test virtual machine which runs CURRENT under Hyper-V. It's amd64 r285198 now. It can't get any response from MS DNS server. Well, it could two or three weeks ago, but after upgrade it's not able to do it anymore. Google DNS answers without problems meanwhile (sic!). What I do: # host google.ru 192.168.25.3 I see that MS DNS (192.168.25.3) server receives these packets, but ignores them. And no matter how my system asks MS DNS. Every daemon can't get response too. I know that nothing was changed in MS DNS server. No doubt. Then I tried different available CURRENT snapshot ISOs. FreeBSD-11.0-CURRENT-amd64-20150630-r284969-disc1.iso - MS DNS does not answer. FreeBSD-11.0-CURRENT-amd64-20150625-r284814-disc1.iso - MS DNS does not answer. FreeBSD-11.0-CURRENT-amd64-20150618-r284544-disc1.iso - MS DNS answers! So something was committed to CURRENT between 20150618 and 20150625. This something ruins communication with MS DNS. Then I tried latest FreeBSD-11.0-CURRENT-amd64-20150630-r284969-disc1.iso on bare metal - MS DNS answered! Looks like that something is related to Hyper-V code. Maybe it changes packets somehow? I can gather and provide more info (tcpdump?) if you ask, it's not a problem! ___ freebsd-virtualization@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"

vt(4) performance on Hyper-V
Hi! Just in case, just so you know. I've tried FreeBSD 10-STABLE r270125 with vt(4) on Hyper-V (Win Server 2012 DataCenter). Its performance is extremely bad (while syscons is ok). Here is video http://www.youtube.com/watch?v=62CIKCJ7bog P.S. vt(4) is a bit faster on VirtualBox though when I tried it last time. ___ freebsd-virtualization@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
Re: Hyper-V
I figured out another operations that cause caclru message appearance, such as 'top -n', car /proc/0/status, etc. But I tried these on 9.2-RELEASE LIVE CD and I saw calcru messages. So it seems like it's not related to brand new hyper-v integrated components. It's related to whole FreeBSD system. Which part?

Re: Hyper-V
So, we catched the bug that caused crash. Thanks to all. Cool! As regards the messages about "calcru": I tried to install CentOS 6.4 on new virt machine on same host system. Linux doesn't have any strange messages about time. I tried to migrate FreeBSD and CentOS virt machines to another host which has another hardware. Same story. For example, try to boot beta-3 in LIVE CD mode. You won't see calcru messages. But if you try to run 'dclient hn0' you'll see calcru message storm for some time. On already installed system I can cause messages by doing service zabbix_server start (even if it's not allowed in rc.conf (!)) But I can start mysql-server, zabbix_agentd, apache22 and it doesn't cause appearance of calcru messages. Any ideas?

Re: Hyper-V
I already tried disabling Hyper-v time syncing, setting kern.timecounter.hardware to different type from kern.timecounter.choice, setting kern.hz to different values. But nothing helped.

Re: Hyper-V driver development status
So, is it going to be included in FreeBSD 10 now? As I can see code freeze for CURRENT is planned on 7 September 2013 (10 days from now). http://www.freebsd.org/releases/10.0R/schedule.html It's not much time. 2013/8/17 Abhishek Gupta (LIS) : > Hi Pavel, > > Thanks for inquiring about the BSD drivers for Hyper-V.

Hyper-V driver development status
Hi all! I'd like to know what's happening with hyper-v driver development in FreeBSD. I know about svn branch but there is no active progress in there. What's the roadmap? Or we are waiting for something? What is the current status of that project? I could do some tests. Or it's too early? I'm looking forward to use it =) ___ freebsd-virtualization@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-virtualization To unsubscribe, send any mail to "freebsd-virtualization-unsubscr...@freebsd.org"
