We use Pydio

I have done a win7>win10 upgrades on about ten machines here at work. No major issues except when for people try to use Edge to do actual work. With 100 or so machines you could just login to each one and goto msn.com, hit the Upgrade button. Or unleash the update on your wsus, as youve suggested.

I have been a BOINC user since 1998; started using seti@home my freshman year using an old compaq laptop with win95 on it. I now run 3 projects on my home network, seti@home, milkway@home, and Atlas@home, they run on my main pc (4930k and 32gb ram, amd r9 290) as well as an amd hexcore system that is much slower.

Ive only used it in an office environment once, at my last job when we got some new killer (at the time)hardware. Loaded up boinc/seti on dual proc dell server with 256GB ram, for 'testing' to make sure it could run at full load for periods of time. It was also fun to see how many work units it could do. My boss said 1 day was enough, so i uninstalled it.
These distributed computing tasks dont use much bandwidth, but they will run your cpu at max, and some of them eat up RAM (Atlas@home is one). There are settings to control all that.
However, running these on work systems is using company resources for personal stuff, unless your boss is huge into distributed computing and science and wants spare cpu cycles spent that way(havent met one yet that does),

Recently i reinstalled Win7 on a pc at home before this rollup was released (back in April i think i did this). From first windows update check to finished with updates was something like 15 hours. 3 hours to check for updates, a few more hours 'downloading' them, then about 10 more hours installing them. I imagine it would be faster with wsus, but still horrible.

are you sending emails from a or other mx records on your domain? If not you dont need to include them. This should work ok for you
I also like hard fails, but others dont.

Watch '100 Latinos Dijeron' on Telemundo/univision(cant remember), its Family Feud but in Spanish. I use it to keep up my spanish skills. I get most of the jokes and almost all of the questions asked. It is on 6pm pst every weeknight.

Rocket League of course.

@aaronstuder
The dvd is for my test lab! that is just an old i7 970 with 24gb ddr3, an old 40gb laptop hdd for OS and 2 2TB seagate drives for storage. I suppose i could have used a usb stick.

SMB support! About time. Only a couple weeks after i got 6.5sp1 installed on my 2 hosts. Burining to dvd now.

Dashrender's post got me thinking, because i really didnt know the answer, having not set any of this up. I rebooted the server Friday about noon, and it refused to POST. I then remembered this winter, about 4 days after i started here there was a power outage at the office, and that none of the servers were correctly hooked up to the ups' to shutdown gracefully.

Ok well, after some more testing Friday due to losing my pool master, i determined the bios on this mobo was bad, and i have replaced the mobo and now there seems to be no problems. I will keep tracking the Windows event log and see if the errors are gone or not over the next week or so.
This happened also when i upgraded the XenServer to 6.5sp1(a few reboots from 6.2). I realized that it kept getting stuck most of the time during post, and i would have to hold down power button til it turned off, then turn it back on, and normally it would boot correctly. The errors i were getting were quite strange, and some online resolutions from citrix or 'the internet' hinted at interrupt remapping being the issue for certain intel chipset. But i didnt have the affected chipset.

Still mystified about XenServer using the broadcom network drivers with Intel nics though. I will dig into this more later on; just glad to have 2 hosts again now instead of 1.

HyperV isnt Xenserver

How to from Citrix on exporting/importing from esxi to xenserver.

Did you remove esxi tools from guest before export? This is important.

My proposed solution, comes from an old bug report from citrix' jira site.
https://bugs.xenserver.org/browse/XSO-241
Not specific to my hardware, but the citrix person here says:

I also notice the broadcom cnic and bnx2i driver's are loading due to you using iscsi on your host.
Can you try running the following commands in dom0 (to disable those modules) and reboot the server:
mv /lib/modules/3.10.0+2/extra/bnx2i.ko /lib/modules/3.10.0+2/extra/bnx2i.bak
mv /lib/modules/3.10.0+2/extra/cnic.ko /lib/modules/3.10.0+2/extra/cnic.bak
mv /lib/modules/3.10.0+2/kernel/drivers/net/ethernet/broadcom/cnic.ko /lib/modules/3.10.0+2/kernel/drivers/net/ethernet/broadcom/cnic.bak
depmod -a

This seems to just rename the modules to .bak files so that they wont be recognized on boot. I assume then that igb would be loaded for iscsi communication and hopefully solve the issue. Not sure what risks there are, if this messes things up badly i could just rename the files again i think and be back to where i was.

Yes, randomly about once a day, all vms on this host will become unresponsive for about 5 minutes. Linux vms go into read only mode, and windows vms spit out this warning as well as some disk io operation warnings. Then it goes back to normal on windows vms, i just restart the linux vms to get them back to normal.

Oh shoot, forgot to say i have upgraded my xenserver host to 6.5sp1 and all updates released until last week.

https://en.wikipedia.org/wiki/Fax

Fax machines are archaic; first one patented 150 years ago. 'New' ones from ATT designed in the mid 1920s. I try to avoid them, though i imagine they will never go away.

@scottalanmiller Fixing lots of things. Trying to fix other things, failing. Im really loving xenserver so far for the almost 4 months ive been using it. Just got a raise, so im feeling good about the work ive done here, so ill be around more often now.

So, i have been dealing with this for awhile, ive got some more info, and a possible solution though i am just shooting in the dark here still i think.
when i run :
lsmod | grep 'iscsi'
iscsi_tcp 18333 20
libiscsi_tcp 21043 1 iscsi_tcp
libiscsi 53218 4 bnx2i,ib_iser,iscsi_tcp,libiscsi_tcp
scsi_transport_iscsi 77023 6 bnx2i,ib_iser,iscsi_tcp,libiscsi
scsi_mod 209749 18 bnx2i,ib_iser,iscsi_tcp,libiscsi,scsi_transport_iscsi,sr_mod,sg,isci,libsas,scsi_transport_sas,libata,scsi_dh_rdac,scsi_dh_hp_sw,scsi_dh_emc,scsi_dh_alua,scsi_dh,megaraid_sas,sd_mo

This seems to show the use of broadcom drivers for my iscsi connections. This host has intel network interfaces. However, my other xenserver host(exact same hardware as problem host) lists the same output for lsmod | grep 'iscsi' and never has this issue.
If i use
lsmod -l | grep bnx2i
bnx2i 55493 0
cnic 77183 1 bnx2i
libiscsi 53218 4 bnx2i,ib_iser,iscsi_tcp,libiscsi_tcp
scsi_transport_iscsi 77023 6 bnx2i,ib_iser,iscsi_tcp,libiscsi
scsi_mod 209749 17 bnx2i,ib_iser,iscsi_tcp,libiscsi,scsi_transport_iscsi,sg,isci,libsas,scsi_transport_sas,libata,scsi_dh_rdac,scsi_dh_hp_sw,scsi_dh_emc,scsi_dh_alua,scsi_dh,megaraid_sas,sd_mod

Not sure why either of my Xenhosts (i took over this environment) are using iscsi drivers for nics they dont have installed. The Intel Gigabit driver is there, just not used for iscsi as far as i can tell.

If i am totally wrong about this please tell me...

I just bought Unitrends for our Xenserver environment about 2 months ago. I have well over 95%(over 99% at the moment) backup success rate with 40 or so vm, using a combo of vm backups, agent backups(required it seems for some vm servers with sql dbs) and sql/exchange db backups. I may be able to help you with your problems. There are some things it wont do in Xenserver yet, like instant recovery for example, but it is working well for me so far.

I checked the storage array before posting, there is nothing to indicate there are any errors there. I also checked Xenserver Tools install on the servers which were affected, and all of the server that went unresponsive had the same warnings in windows even viewer. the one server that does not have xentools, has no errors or warnings during that time. The version of xenvbd SCSI Adapter is 7.0.0.120 on more than one of the servers with the problem.

this is what im looking at on one server
