hi, let`s say that a guest has 1GB memory.Vmware hypervisor will give to this guest at a certain time only the needed memory-i mean the guest will receive let`s say 500MB next 800 MB RAM depend of the memory required. free -mh total memory 1GB the real RAM provided by hypervisor can vary until shutdown this guest.right?

Hi, I can update ILO or IDRAC from esxi using the ipmitool.right? THe same i can upgrade the firmware or BIOS of server using tools from vendor.right? Service processor and the Server come together so sometime is needed to upgrade ILO from SP and simetime os needed to upgrade BIOS.right?

hi, An esxi host can not enter maintenance mode if VMs are up.Is this valid for every esxi version? When upgrade esxi then esxi is put in maintenance or we boot from dvd,upgrade and reboot.right? [Unnecessary "spoiler" removed by moderator]
i reboot from dvd so once the reboot begin that there will be no i/o traffic.so no need of maintenance.right? if i perform things on esxi then i put in maintenance.after ecerything done i reboot es...

i reboot from dvd so once the reboot begin that there will be no i/o traffic.so no need of maintenance.right? if i perform things on esxi then i put in maintenance.after ecerything done i reboot esxi.once rebooted this esxi is in maintenance? if there are no VMs on this esxi then no maintenance is necessary.right? After i reinstall new ESXI then i must register VM again with this host?

hi, i like to reinstall esxi. Connect to ILO; Select Remote Console Media/Java Integrated Remote Console; Mount ISO from local drive; Put in maintenance ESX; Reboot server ESX; Press F11 Boot Menu; Select 1 CD-ROM; Upgrade ESXi, preserve VMFS datastore; F11 upgrade; Remove Virtual Media installation files; Check version is VMware ESXi 6.7.0 in ILO interface; Test if network connections are ok i mean put in maintenance esx then reboot work?

hi, i think that heartbeat traffic is better to travel over different physical nics ,not on the same physical nics that carry the data traffic. so if we have a different vswitch on every host uplinked by 2 different nics-i think is better.

hi, in esx cluster if this is not HA,then a VM from a host within this cluster that fails,this VM will not be brought up on other host.right? So if i have 2 VMs with linux inside and the 2 linux nodes form a cluster,if the 2 VMs are on the same host and this host fails then the cluster is down.right? I have VMs that run linux cluster. The 2 NICs that carry heartbeat traffic are better to connect to a separate vswitch in every host?

hi, Is it safe to use vmotion to move a VM (with linux that has nfs or cifs shared mounted inside VM)? Is it safe to move with vmotion a VM that is very high loaded?either the i/o traffic is very high or the cpus are very loaded. if there inside VM is high i/o traffic can be a delay in moving the VM to other host?
i talk about host utilization.if cpus average load is hight that is better to use cpu reservation.right? or if i do not need drs then i use cpu affinity.right?
hi, when the workload is high (the average cpus load >80%) then is better to run any VM on a certain cpu -affinity.right? by pinning the VM to certain cpu ->affinity.

hi, if i like to monitor VMs on esxi with zabbix or any other monitoring tool we use the ip of monitor port.this port work over an uplink vmnic-bonding is better that does not has any ip. the ip are only at the port level (monitor port ip,data port ip,so on).right?

hi, i have on host vsw1 with vmkernel and monitor traffic and vsw2 with i/o data traffic. when i create a VM in order that this VM to be used by vmotion and to be monitored is necessary,if i use an vmnic then i must setup 2 vlans on this vmnic(inside VM)-one for monitor and one for traffic data?
